@nicdex About a week ago, our #dokuwiki server was DDos'd by 10'000 costly diff requests per hour, from about 9950 unique IPs all over the world. Worse, some requests just timed out, saturating all apache connections. Used @splitbrain s botchecker and reduced Apaches timeout to 15 secs.

Smooth sailing since then, and after two days, the request flood receded.
