Sorry, folks. This seems to be my month for Internet screwups. Yesterday, I installed a new firewall at a different IP address than I had been using for this blog. But I didn’t install the SSL certificate on the firewall. So, after the DNS changes propagated, everybody started seeing scary warnings about the security of the site. It should be fixed now.
Let’s hope these things don’t come in threes.
Added later: it appears that comments are getting blocked by the new firewall. If that’s happening to you, know that I’m working on it. Thanks for your patience.
