At night on 09.08.2013 from 19:30 until 02:30 (GMT) was not available database of IP blacklist, Email, domain addresses. As a result of the specified time the efficiency of spam filtering was below the multiyear average. The most heavily accident affected users with modules phpBB3 version 3.5.10 and below, along with the WordPress 1.4.4 and below.
The accident is caused by physical hang database. We have made several improvements on servers automatic moderation, in particular increased the lifetime of the data in a local cache server up to 12 hours (was 1 hour), it will allow to avoid similar accidents in the future.
Thanks!
