Note: Tom Keating posted on his gadget's blog about a Skype outage that happened yesterday.  I would have to say this is the first time in my recent memory that I have heard of a Skype outage.  I must of been too busy fielding phone calls on my Asterisk PBX to notice
 
Tom's Post:
"Skype is experiencing a major outage. My fellow TMC co-workers noticed it late Wednesday when they couldn't IM fellow workers. TMC's Dave Rodrqiguez told me that he went home for the day, signed into Skype from home and was bombared with a ton of Skype IM messages that didn't go through earlier."
