Looks like my hosting company decided to move my blog from a 32 bit OS to a 64 bit OS, breaking the PHP CGI in the process. Thus, my blog was offline for around 20 hours or so (rough guess).

Support claimed I had a “custom” PHP install, which I think is not the case. Anyway, I had to copy the 64 bit PHP CGI binary from their system location to my blog location, update a pointer and now everything is good again.

Apologies all around for going “dark” for a while.
