My entire domain (goodness that sounds regal) was down, and it was completely my fault. It’s back up now—thanks more to people who know much more than I about these things than to the self-flagellation I’ve been engaged in since yesterday morning—so website and email should be functioning normally again.
If you’ve tried to reach me, please accept my apology and re-send your message. (There’s a contact form here if that’s easiest for you.)
