Intermittent outage

Sorry if you’ve been unable to access the site over the last 48 hours – there was a problem with one of the DNS servers that handles which was directing people at an old server for the site. It’s fixed now.

In case you want the details – the primary nameserver for has been upgraded and reinstalled, but the BIND configuration I put back was a copy from several months ago before I migrated from Amazon to Rackspace. The serial number on the zone was lower than that on the secondary servers for the domain, so none of the secondaries picked it up. It’s a case of luck as to which server you get sent to, so there was roughly a 1-in-5 chance of picking up the server with rogue information.

Backups are good, but restoring the right one is even better!
