markHi, sorry for the downtime. The main incoming server that everybody connects to before getting farmed off to one of the other servers crashed, according to Slicehost. As expected, the backup server took over and the site was back up a few minutes later.
The followup problem (seeing the Apache default page) happened when the primary server came back up and it "took over" the site again. But of course, it took over and wasn't quite ready to give everybody the right stuff and threw some errors.
It should be all good now. If I hear anything else from Slicehost I'll let you know. Sorry for the inconvenience, I hope we didn't eat many posts. :(
