Hi,

At about 22:30 UTC last night (Tuesday) one of our power circuits went
down for about 15 minutes.  This affected one node of the HA cluster
which was hosting the following services:

	Sun Grid Engine master server
	tsbot IRC bot
	DNS recursor
	MySQL server for sql-toolserver
	MySQL replication support infrastructure
	LDAP server

All services failed over to the other node and were online again within
22 seconds.  However, MySQL did not respond well to losing its
replication connection and had to be restarted manually, causing about
30 minutes replication lag.

	- river.
