It's worse than I originally thought. At first, I thought GoDaddy's site was down. Then I heard a LOT of its customer sites were down.
A ton of GoDaddy domain name resellers are offline, too. This is a big deal. Lots of money will flow to GoDaddy's competition today.
I hate to see anybody harmed by jerks who just want to wreak havoc—I do like friendly competition but this isn't it.

I'm not one to beat on a dead horse, but it may be high-time to consider a Host Gator account. You can get 25 percent off by using this coupon code: IMMuscle25percent
Good luck. Hope you weren't affected.
