A quick recovery of the blog was functional by noon, and had its appearance restored 99% before the end of the day. I was extremely cautious on this one, as there were some abnormal log entries that indicated the remote possibility that a bad update or malicious software might have corrupted the site. So, rather than patching a potentially corrupted site, I put the site in deep freeze, and built it again from reliable sources. All seems well, so far, and I look forward to digging in and determining the root cause.
