We're having some problems with our sign in server, so you may not be able to sign in to the Skype application or to your account as normal. [2009/01/21@1746UTC] If you're already signed in to the Skype application on your computer or mobile phone, you should be able to call/IM/etc as normal. This is only affecting people who aren't already signed in. [2009/01/21@1752UTC] Our forums are experiencing heavy traffic and so access may be slower than usual. Apologies! For more updates, watch this space or follow @skype on Twitter. [2009/01/12@2002UTC] We've made some changes which should improve things. Stand by! As soon as I have more information, I'll update this post.
