What caused the failure of a forum? Was it an hackers attack?

"The slowness was coming from an excessively high number of idle connections, which may or may not have been related to a global denial-of-service attack that affected thousands of sites last week. Whether or not that was actually the case for us is hard to tell, but in any case, the end result was that we ended up with a server so broken, it needed to be wiped out completely and reinstalled from scratch."

I already know that, I'm just wondering if, they are any details what was the cause.
