Italian Software Maker Contests Microsoft’s Purchase of Skype

September 29th, 2011

Reviving arguments that have dogged Microsoft in Europe for nearly two decades, an Italian software maker is asking European officials to block Microsoft’s $8.5 billion purchase of Skype, the Internet phone service, unless it is removed from Microsoft’s ubiquitous Windows Office platform.

In the past, the European Commission has been sympathetic to complaints about Microsoft’s strategy of “bundling” popular applications with Windows, eventually requiring the software maker to make concessions on its media player and Internet browser.

But legal experts were split over whether the latest complaint, filed Sept. 20 by Messagenet, a company based in Milan that is a rival to Skype Internet’s phone service, would complicate or prevent European approval of the takeover, which would be the largest in Microsoft’s history and the largest takeover in the technology sector this year.

“These types of complaints from competitors are to be expected,” said Denis Waelbroeck, an antitrust lawyer at Ashurts in Brussels. “I would expect that the commission will look at this seriously, but I think that in the end, the officials will reach their own independent decision. This doesn’t mean the complaint will be upheld.”

Joaquín Almunia, the E.U. competition commissioner, plans to make his decision on the acquisition public on Oct. 7. A spokeswoman for Mr. Almunia, Amelia Torres, on Wednesday declined to comment on Messagenet’s complaint. In general, she said the commission considered all submissions from competitors in antitrust cases.

Mr. Almunia, a Spanish economist, had been competition commissioner for less than two months when his office approved Microsoft’s takeover of Yahoo’s search business in February 2010. A Brussels antitrust lawyer, who did not want to be identified for fear of alienating a potential client in Microsoft, said the Italian complaint could scupper the deal.

“I would certainly say this kind of complaint, if it raises new issues that the commission has not previously considered, may derail the deal or, at least delay approval,” the lawyer said. Mr. Almunia could be persuaded to extend his present review into a more exhaustive second phase, which could take months or even years.

Or, the lawyer said, Microsoft could seek to delay an immediate decision and buy time by requesting an extension to prepare an answer to the complaint. Jesse Verstraete, a spokesman for Microsoft in Brussels, said the company declined to comment on the allegations in the complaint from Messagenet.

“The proposed acquisition is still undergoing regulatory review and we are working closely with the agencies,” Mr. Verstraete said. “Until all regulatory approvals are obtained, it is business as usual at Microsoft and at Skype.”

Besides asking Microsoft to “unbundle” Skype from Windows, Messagenet is urging European competition authorities to require Microsoft to effectively open Skype’s Internet phone network, which had 124 million regular users in June, to the services of rivals. Messagenet is asking the commission to do this by requiring Microsoft to disclose the confidential computer coding that would enable rival services to connect calls to Skype users.

Skype’s communication software does not operate with rival services. In May, after Microsoft announced its plans to buy Skype, the managing director of Messagenet, Andrea M. Galli, said he had written to Skype requesting the secret coding that would let the services interconnect, according to a copy of the complaint that Messagenet filed with the commission, and which was seen by the International Herald Tribune.

Mr. Galli said Skype never responded to the request.

Less than three weeks later, Skype ended its partnership with Digium, a company based in Huntsville, Alabama, whose software had enabled users of an open-source Internet phone service, Asterisk, to call and be called by Skype users.

At that time, a Digium product manager, Rod Montgomery, lamented in a company blog that Skype for Asterisk, the Digium software, had been a “strong and steady seller.”

After Skype canceled the partnership, Digium stopped selling Skype for Asterisk on July 26. Mr. Montgomery said Skype had guaranteed to support and maintain the software for existing users for only two years, honoring a provision in its original contract with Digium.

In his complaint, Mr. Galli said the Digium incident showed Microsoft’s intention to keep Skype as a closed, proprietary software application, unavailable to rivals.

“The first effects of the proposed merger will be an even more rigid approach to interoperability of Skype services so to exclude competitors from the market,” Mr. Galli wrote in the company’s complaint.

The U.S. Federal Trade Commission approved Microsoft’s purchase of Skype on June 17, arguing that, with rival Internet phone operators Google Talk and Apple FaceTime, there was sufficient competition to let Microsoft’s purchase proceed.

But that rationale may be less persuasive in Europe, where none of the big global sellers of Internet video communication services are European companies, and where regulators have a track record of challenging Microsoft’s bundling strategy.

In 2009, under pressure from European officials, Microsoft agreed to distribute a ballot screen on Windows allowing users to choose their default browser from a list of 12, including Windows Internet Explorer.

The agreement settled a complaint that had been filed by a small Norwegian browser maker, Opera, which had attracted support from Google and Mozilla, the makers of the Chrome and Firefox browers, respectively.

The ballot screens, which Microsoft began distributing in early 2010, have sped the erosion of its browser share in Europe. Internet Explorer’s market share in Europe slipped to 46.3 percent in April from 55.7 percent a year earlier, according to AT Internet, a research firm based in Merignac, France. During the same period Google’s Chrome, Apple’s Safari browser and Opera all gained market share.

In 2007, the commission required Microsoft to sell a version of Windows XP in Europe without its own media player, a condition it imposed to resolve a decade-long legal clash that ended with Microsoft’s being convicted of antitrust violations and paying more than $1 billion in fines and penalties. But that remedy largely failed as European consumers rejected the stripped-down Windows version, which Microsoft was allowed to sell for the same price as the full version.

Skype Picked Microsoft’s Pocket, But the Software Giant’s Credit Position Is Largely Unchanged

May 11th, 2011

We don’t believe Microsoft’s MSFT $8.5 billion acquisition of Skype will significantly alter the firm’s credit quality and, as such, we don’t plan to change our AAA rating. While the deal comes at a steep price–more than 30 times Skype’s adjusted 2010 EBITDA–this is more of a concern to equity investors. Microsoft has generated more than $19 billion in free cash flow during the first three quarters of fiscal 2011. Even after returning $14 billion to shareholders via dividends and buybacks, net cash has increased to $38 billion from $31 billion at the end of fiscal 2010, with gross cash sitting at $50 billion. Further, the company is paying for Skype with overseas cash, which avoids a repatriation tax hit.

The reduction in cash on the books has little impact on our credit rating model. Prior to the deal, we had expected Microsoft to generate enough cash to meet its obligations roughly 17 times over during the next five years. Removing the $8.5 billion it will pay for Skype, without any incremental cash flow the firm will provide, takes that ratio down only modestly to about 16 times.

We don’t plan to change our Business Risk assessment of Microsoft as a result of the Skype acquisition, as we believe the deal makes strategic sense. Microsoft hopes to leverage Skype’s peer-to-peer communication technology prowess to enhance the value proposition of its business and consumer collaboration products and services. Some compelling services that could emerge include video conferencing via Kinect, video chat on Windows Phone devices, PCs, or tablets (similar to Apple’s AAPL FaceTime service) and usage of Microsoft’s Lync and Skype to communicate with users external to enterprise customers’ organizations. That said, we would get concerned if Microsoft’s management made a habit of overpaying for acquisitions on a regular basis.

Skype for Android leaks user data

April 18th, 2011

A flaw in Skype for Android could let criminals harvest private information from smartphones, including the user’s name and email address, contacts and chat logs, the Internet calling software maker confirmed Friday.

One security researcher called it “sloppy coding” and a “disrespect for your privacy.”

Last week, Justin Case, a regular contributor to the Android Police blog, disclosed that Skype on Android does not block access to a number of sensitive data files stored on the handset.

The files contain a wealth of information about the Skype account and the smartphone’s owner, ranging from full name and date of birth to alternate phone numbers and account balance. Also accessible, said Case, are instant chat logs and all Skype contacts.

“Skype mistakenly left these files with improper permissions, allowing anyone or any app to read them,” said Case. “Not only are they accessible, but [they're] completely unencrypted.”

Case created an Android application that demonstrated retrieving the unsecured data, and warned that hackers could do the same.

“A rogue developer could modify an existing application with code from our proof of concept, distribute that application on the [Android] Market, and just watch as all that private user information pours in,” Case said.

Case’s concern is well-founded. Last month Google yanked more than 50 malware-infected apps from its Android Market, while three weeks ago Czech security company AVAST said a different rogue designed to shame software pirates sent personal information to the maker of the “Walk and Text” app.

On Friday, Skype acknowledged what it called a “privacy vulnerability” in its Android client. Although it promised to address the problem, it did not spell out a timetable.

“We are working quickly to protect you from this vulnerability, including securing the file permissions on the Skype for Android application,” said Adrian Asher, Skype’s chief information security officer, in an entry on a company blog.

As of late Sunday, the Skype app for Android had not been updated.

Asher also urged users “to take care in selecting which applications to download and install” on their smartphones.

Chet Wisniewski, a security researcher at Sophos, didn’t think much of that advice.

“How you would implement that advice is difficult to know, as an application wishing to steal your Skype information doesn’t require special permissions,” Wisniewski said in a Sunday blog.

Instead, Wisniewski said the safest move by Android users would be to delete Skype from their smartphones.

Wisniewski argued that the flaw Case uncovered was not really a vulnerability, disconcerting as it was. “This could simply be written up as sloppy coding at best, or disrespect for your privacy at worst,” he said. “[But it] makes one wonder about the Skype for iOS application. Is it safer in Apple’s App Store?”

The separate Skype Mobile on Verizon app is not affected by the privacy snafu, said Case.

Skype outage blamed on bug in older software version

January 2nd, 2011

Skype’s outage last week is was caused by a bug in an older version of its software, used by more than half of its users, that overloaded its servers.

Lars Rabbe, Skype’s chief information officer, said on the Internet calling company’s blog that its “Skype for Windows client (version 5.0.0152)” servers crashed last Wednesday and Thursday after a group of servers responsible for offline messaging became overloaded.

Newer versions of Skype’s software, such as version 5.0.0.156, and older versions of Skype were not affected by the initial problem, Rabbe said.

But because so many Skype users had version 5.0.0152, the server crashes caused about 25% to 30% of the company’s “supernode” computers — which serve as connection points in its network — to fail. That caused users of other versions to fall victim to the outage as well, he said.

Skype has released a software update for version 5.0.0152 in an effort to keep such an outage from happening again.

“We are learning the lessons we can from this incident and reviewing our processes and procedures, looking in particular for ways in which we can detect problems more quickly to potentially avoid such outages altogether, and ways to recover the system more rapidly after a failure,” Rabbe said.

The blog post ended with an apology to customers — which comes after the decision to reimburse paying Skype users affected in the outage.

“We know how much you rely on Skype, and we know that we fell short in both fulfilling your expectations and communicating with you during this incident,” Rabbe said. “Lessons will be learned and we will use this as an opportunity to identify and introduce areas of improvement to our software, further assess and invest in capacity and stability, and develop better processes for outage recovery and communications to our user base.”

Skype outage caused by buggy software

December 30th, 2010

The Skype outage that caused an interruption to its service earlier in December was due to a fault in a version of its software client, the company’s chief information officer has explained.

On 22 and 23 December Skype’s underlying peer-to-peer network crashed, cutting service for consumer and enterprise users of the internet telephony service.

“On Wednesday, December 22, a cluster of support servers responsible for offline instant messaging became overloaded. As a result of this overload, some Skype clients received delayed responses from the overloaded servers,” Lars Rabbe, Skype’s chief information officer, wrote on the company’s main blog. “In a version of the Skype for Windows client (version 5.0.0152), the delayed responses from the overloaded servers were not properly processed, causing Windows clients running the affected version to crash.”

Around 50 percent of Skype’s global users were running the 5.0.0152 version of the software client. The crashes caused around 40 percent of the affected clients to crash. This ultimately took down 25 to 30 percent of all publicly available “supernodes”, Rabbe wrote.

Supernodes are part of the backbone of Skype’s distributed peer-to-peer communications network. Supernodes provide the addressing details of other Skype clients, route data, create local address clusters and help to connect different Skype clients with one another.

Each time a supernode failed, it created a cascading effect, Rabbe wrote. The responsibilities for the failed supernode were passed to the remaining supernodes, which then came under such a load that they began to shut themselves down as they had exceeded expected operational parameters, he continued. Stress on the remaining supernodes was heightened as users who had experienced crashes on their 5.0.0152 Skype client were restarting the software, placing additional strain on the remaining supernodes.

Traffic to the supernodes was about 100 times what Skype would have typically expected from that time of day, Rabbe wrote.

“Regrettably, as a result of the confluence of events server overload, a bug in Skype for Windows clients (version 5.0.0.152) and the decline in available supernodes Skype’s functionality became unavailable to many of our users for approximately 24 hours,” Rabbe said.

Skype was able to restore service by injecting thousands of “mega-supernodes” into the Skype network over the course of 22 December. The mega-supernodes did the jobs typically assigned to supernodes, while helping to stabilise other supernodes in the network, Rabbe wrote. Resources normally dedicated to Skype’s Group Video Calling (GVC) features were used to deploy new supernodes and this caused downtime in GVC, which was restored by 24 December.

In light of the outage, Skype is going to look at the ways it can provide software updates to users to assure that all are up-to-date and will examine its testing process for new software, Rabbes wrote.

Skype blames recent outage on buggy software

December 29th, 2010

In a blog posted today, Chief Information Officer Lars Rabbe explained the house of cards that took down the service the morning of Wednesday, December 22, and kept it offline for many until the following day.
On December 22, a number of support servers that handle offline instant messaging became overloaded, according to Rabbe. Because of that, some Skype clients didn’t receive responses as quickly as usual. A bug in one particular Skype client for Windows (version 5.0.0.152) prevented it from processing those delayed server responses, causing the client software to crash.
Since Skype is a peer-to-peer network, any PC running the client software can act as a node to route and process traffic. But PCs can also be tapped to serve as supernodes, which help maintain connections for multiple users.
Since about half of all Skype customers around the world were running the buggy client version, the resulting wave of crashes triggered failures in 25-30 percent of Skype’s supernodes. That put extra strain on the rest of the supernodes, causing them to start failing. Despite the efforts of the tech folks at Skype to disable the overloaded servers and stop the client requests, the entire Skype network eventually shut down.
“Regrettably, as a result of the confluence of events–server overload, a bug in Skype for Windows clients (version 5.0.0.152), and the decline in available supernodes–Skype’s functionality became unavailable to many of our users for approximately 24 hours,” wrote Rabbe.
To get the service up and running again, Skype engineers spent that Wednesday introducing more and more instances of the Skype client software (the non-buggy version) into the network to generate more and more supernodes. That helped the network gradually recover, allowing the majority of Skype users to get back online by Thursday.
What is Skype doing to make sure an outage like this won’t happen again?
First, Rabbe says the company had provided a fix (version 5.0.0.156) to the buggy software before the outage occurred, but many people hadn’t yet installed it. As such, Skype will be reviewing its process for automatic updates. Second, the company will look into ways of detecting and recovering from such problems much faster. And third, it will evaluate its testing processes to better find and avoid bugs that could take down the entire system.
Rabbe also acknowledged the company’s failure to prevent the outage and its lack of communication when the service was down.
“Lessons will be learned and we will use this as an opportunity to identify and introduce areas of improvement to our software, further assess and invest in capacity and stability, and develop better processes for outage recovery and communications to our user base,” Rabbe wrote in closing.

Skype Creates Custom Video Chat Software for Refugee Workers

December 7th, 2010

Despite its uncertain future, VoIP company Skype has guaranteed itself at least a small core of customers by partnering with the United Nations High Commission for Refugees (UNHCR) to provide a custom, low-bandwidth video chat service to aid workers around the world. Aid workers supporting refugees are often shipped out with little notice, and can spend months at a time separated from friends and family. Skype is doing what it can to support these aid workers by creating a customized version of its VoIP software that can keep workers in touch with friends and family in areas where Internet connections are often slow and unreliable.

Skype has successfully tested the low-bandwidth communication software in Iraq, Sudan and Afghanistan, and is now opening it up to aid workers in Algeria, the Congo, Kyrgyzstan, Somalia, Sri Lanka and Uganda. By the end of 2011, Skype hopes to have connected 80-percent of the UNHCR’s staffers. Skype will also be hosting a button that will allow regular Skype users to donate to charities supporting refugees. The company has been struggling in recent years to keep up with the competition, and some are wondering if its future lies with bespoke software. We’re not sure that creating custom VoIP solutions is enough to keep Skype relevant, but working with the UNHCR certainly can’t hurt its reputation.
