Appologies to vtcpool.co.uk users - the new server we've migrated to has some issues. There is likely to be an extended period of downtime - not only will the recovery/troubleshooting take some time, but I also have to go away for a few days. I'll do my best to get it up and running before that happens, but it's possible the downtime will extend over the weekend if I can't get it done in time.
There are multiple, off-site backups of the database and wallet. No coins are at risk, hopefully you've all failed over somewhere else for the time being.
