Many Skype users have been affected this morning by a glitch which has rendered the service unusable or only semi-usable. The BBC says that problems have been reported in Japan, the UK, and Australia, and that Skype support staff have promised a "quick fix." A message on the Skype page says "f you're signed in to Skype, you will not be able to change your status and your contacts will all show as offline even if they are online. As a result, you won't be able to start Skype calls to them.. A small number of messages to group chats are not being delivered, but in most cases you can still instant message your contacts.. If you aren't signed in to Skype, you may be experiencing difficulty when attempting to sign in. Any changes to your Skype account such as your Credit balance or your profile details might take a little while to be displayed."
