I've been using TypePad for my blog/site since 2005.
After 9 years of nearly 24x7 up time, SAY Media (the company that owns the TypePad service) got hit with a nasty DDoS attack.
My blog has been down for two days and others have been down (or up and down) for close to a week.
Really stinks.
Apparently, SAY Media is working with the FBI. I hope they catch the crooks.
