Apparently, the web host had a hard drive crash earlier, which knocked us off the web for a bit.
Unfortunately, they had to restore from a backup that wasn’t exactly current, so some posts and comments have been lost. I was able to restore the posts from web feeds, but all comments past a certain point have been lost permanently, unfortunately. Sorry about that!
We may have to consider a new web host before too long, as this is annoying!
UPDATE (12-29-2007): I’ve added some backup redundancy via a couple of scripts we’re now running via a cron job. Details are here, for anyone who is interested in a similar backup system for their own blog (recommended after our recent experience).
