Actually it wasn't even a DDoS. MPGH had just switched servers, and we were updating our DNS when... A larger site than ours DNS fucked up, and was redirecting all hits to us. Like the site was called FreeOnlineShows or something. Anyhow, for 6 or so hours, the site was giving us massive hits, and like people were adding Dave to MSN asking what happened to the site. The scary thing was, Google updated their index an hour after it happened. And soon, we were getting hundreds of keywords in hits to people wanting to watch 300 and Star Wars online. A few topics were made, a couple questions were asked, but not much.
I learned something very valuable, what to expect when you have a huge site (top 10000 sites in the world).
