An update on the downtime which has been affecting many of you around the world: the ability of one Skype user to find another relies on what we call ‘supernodes’, and yesterday, a number of these failed due to a software issue, which we’ve now identified. Our engineers are working to resolve the problem.

Millions of you are already reporting that you can now sign in to Skype normally, and we estimate that there are already almost 5 million people online. As a guide, this is around 30% of what we’d expect at this time of day – and that number is increasing all the time. 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.

It’s worth noting that our enterprise product, Skype Connect , is working normally, though Skype Manager and our other web-based functions will continue to stay offline for a little longer. Additionally, features like group video calling will take longer to return to normal.

We’re sincerely sorry for this disruption – like you, all of us at Skype rely on Skype every day. We understand just how important Skype is to your friendships, family, and work, and so are particularly aware of the impact of rare problems like this. We’re working hard to restore full functionality to the Skype software, and hope to have more information to share soon. You can also follow @skype on Twitter for further updates.
