Fighting a Denial of Service Attack
Quick overview: one of the sites my company runs has been targeted, and we've been getting slammed since about 2am. They come from all over the world, with various user agents. No obvious pattern I can discern. We've been swatting them manually, and we throttled that domain so it can't take our entire network out like it was doing this morning, but the targeted domain is still crawling.
Has anyone here been a target of a confirmed denial of service attack? If so, do you have any wisdom to share?
