Much like the previous one: viewtopic.php?f=5&t=1157

The site was again swamped with random forum requests (600-1000 in a few minutes),
at about 1.38am CEST (so 7.38pm EDT for example),
causing the server to run out of memory, which crashed the database server.

This explains the "can't connect / mysql" errors people were seeing.

This attack again was from China.

update: I added some new "DDOS mitigation" features,
let's hope this helps [namaste]
