Otakubell.com has NOT been working well lately. At first I thought it was my fault – I had made a change to my mail server configuration and caused a nasty sort of feedback loop, which I didn’t notice until my girlfriend showed me a bounce message. I fixed the problem, and all seemed well for 2-3 days. But then the server seemed to just keep timing out for no obvious reason, and I didn’t have time to explore the issue. So, I rebooted a few times, and the temporarily fixed it.
Finally I had time to address the issue and looked at my logs – bingo. Someone from bigpond.com.au was hammering one file over and over, like hundreds of times per minute. Charming. I had mod_evasive installed, but not activated. Well, I activated it, and all has been well since.
5/9/13: Well, not quite. It turns out there was some database corruption going on as well, and pretty much every page on otakubell.com is database-driven. I repaired the database, and optimized it while I was at it.
