Their site is down. Does this happen often?

Search the forum. They've been battling with DDoS attacks and other issues over the past 9 months or so. Unfortunately random downtime for hours on end is not uncommon.

They seem to be back up now. But yes, they have experienced a number of DDOS issues. I've heard that they have been working to resolve those issues, hopefully that is the case and this little "burp" today was just a minor one.

2Co has gone offline for me a couple of times, but its never down for more than a hr at most
