Why was the site down yesterday ?
WebFaction had us scheduled for a server move. They sent me an e-mail weeks in advance, but I forgot that our DNS setup has the IP addresses for the hosting configured manually, so I had to adjust that yesterday after realizing the site was inaccessible. On the plus side, we now have 100GB of disk space available on our account and our hosting costs have been reduced, so we're good for another 38 months.
