Skype Outage Still Hitting Millions of Users
Millions of Skype users are still struggling to connect more than 24 hours after a supernode failure
A staggering 40 percent of users are still unable to connect to the VoIP service Skype.
Nearly 24 hours after several computer servers in its P2P network crashed, Skype appears to be restoring service rapidly after suffering an unspecified “software issue.”
Skype Chief Blogger Peter Parkes said around 2pm GMT (7am EST) that while there are roughly five million people online, it was only around 30 percent of what the company would expect at that particular time.
By 4pm GMT (9am EST), Parkes said in an update, that number had doubled to more than 10 million, or 60 percent of total users Skype typically sees online then.
That means Skype remains unavailable for about 40 percent of users.
Millions Offline
“Unfortunately, it’s not possible for us to predict on an individual level when you’ll be able to sign in again, and we thank you for your patience in the meantime,” Parkes added.
Parkes said that while Skype Manager, group video calling and other web-based tools remain offline and instant messaging and online status are slow, the company’s Skype Connect enterprise product is working normally.
Skype, used by millions of users to make free or low-cost long-distance calls from their PCs and phones, began failing for users around 16:00 GMT (11 am EST) on Wednesday 22 December.
Parkes said that after the company engineers noticed that the number of users online fell, it found that its “supernodes” had failed. Supernodes are clusters of computer servers linked by peer-to-peer networking software.
Skype employs millions of connections between supernodes, which are virtual phone directories, and phones.
Supernode Failure
When a user clicks to place a call on Skype and the app can’t locate a user’s computer or phone, it will attempt to ping a supernode to connect the call. When the supernodes conked out, millions of people were unable to make calls.
Dan York, director of conversations at Voxeo, provided a detailed explanation of supernodes on his DisruptiveTechnology blog here for those interested in Skype’s network architecture.
“We’re working hard to restore full functionality to the Skype software, and hope to have more information to share soon,” Parkes added.
