Yesterday afternoon, we upgraded MySQL on the server. Everything seemed fine. Last night, just after midnight my time, MySQL and PHP decided to stop talking to each other, leading to the error message many of you saw both here and on the forums. Apparently there was an incompatibility between the new MySQL shared libraries and PHP. Why this didn't crop up immediately when we upgraded MySQL, who knows. The fix was to force the installation of the old libraries alongside the new, so that they're both there for PHP. We'll also be upgrading PHP soon, which should solve the problem for good.
Sorry for the downtime...I'm feverishly working on some hint postings now, so I hope to have a few up this morning yet.
