Http spam?!

Over the last few days I’ve had thousands of requests from a small number of IP addresses. My bandwidth usage had doubled and when I logged on to find out why, I was dissapointed to find it wasn’t a huge surge in new visitors! :p

I’ve since blocked the IP’s in question but, is this common? The main culprit was but not a lot comes up in a search on google for it. The IP resolves to a russian website that looks like it could be a web host or a portal, nothing that looks suspect anyway! Very strange.
