Linux server WWW-27 found itself under very heavy load this morning. We have rebooted the server and continue to monitor the situation. We apologise for the inconvenience.
Some websites were showing database connection errors. We are rebooting and investigating.
Update 07:20 GMT
All websites are back online. There is still residual slowness while the server catches up with the mail queue. Things should be back to normal soon.
Update 07:40 GMT
The mail queue is now up to date (except for message that have remote delivery problems in any case). All services are back to normal.
