Intermittent Service 2012-06-10

We suffered what appears to have been a volume spam attack between 04:50GMT and 11:00 GMT this morning.  This caused intermittent access to various services during this period.

We have adjusted some of the thresholds at which our various counter-measures trigger and reinitialised some trend databases which has restored normal service and should maintain it whilst we examine log files and system metrics to determine how best to ensure there is no repeat.

Please accept our apologies if you experienced this intermittent service.
