In working on the servers, some apache config files were made inoperable. This is on a misc. services computer named Singer. This is the host for our blogs, as well as some other web-facing info. As such, the cached blogs are affected, but not the tech blog. (It was, but it was the easiest to get back online.)
Apologies for any annoyance this single server downtime may have caused anyone. Rest assured, it will be fixed and steps will be taken to prevent it from occurring in the future.
