If you happened to visit this site between around 5:00PM MST July 14 and 10:05AM today, you probably encountered an unhelpful “Internal Server Error” message. Sorry for any inconvenience or puzzlement. I was reconfiguring something on the server and inadvertently broke something essential. Naturally this happened shortly before some friends arrived for dinner, so I wasn’t able to address the problem until this morning. I’m still not exactly sure what I did wrong but I was able to restore the entire domain from an automatic backup. (Yes, there’s a little lesson there.)
