DDoS

Well, I had a DDoS on my server at home this week, more or less.

There’s a thing called Referer Spam which basically poisons your webserver’s logfiles with false referer information, and then your blog displays it. This gets the referer’s websites higher rankings in search engines like Google.

So, since they’d been poisoning it for a long time, the logfiles had gotten huge, and were causing each page request they made take over a second of CPU time. Since they were making >10 requests a second, my server couldn’t keep up. The load went well over 150.

So I’ve taken measures so they can’t mess it up again.

Of course, all this happened on the old blog. This blog didn’t go down at all.
