Skype, the most popular VoIP (Voice over IP) service on the planet, has been down for many users for almost a day now. Users either can't log into Skype or if they can, when they try to place a Skype call they're told they're offline. It's the same if you're on the desktop or using the iPhone app. You just can't connect.
We typically use Skype to record our iPhone Live! and iPad Live! podcasts, so last night we had to scramble to find an alternative (we ended up using iChat voice) but for businesses that have come to rely on Skype for critical communications, it was a cold reminder that no service is immune to outages.
Do you use Skype? How has the service worked for you over the last 24 hours? What alternatives have you come up with in the meanwhile?
