We're experiencing some technical difficulties with our webhost, TextDrive. Normally they provide excellent service with good support response. This time, however, they've undertaken a big combined host + server move. It's broken the script I use to publish my site and they're not responding to my request for help.
In the meantime, I've reverted to a static rendering of my site. All of the content should be here, but there's going to be a few weird rendering issues until this all gets worked out.
Update, 2 Sept: Moments after I posted this entry, they fixed the problem. Still, if you've had trouble accessing my site for the last few days, this is why.
