For the last couple of weeks malicious bots have been hammering the ISFDB server almost non-stop, which made it effectively unavailable except when the bots took brief breaks.
On top of that, earlier today we learned that the PHP programming language, which is used by the ISFDB Wiki as well as by millions of other Web sites, has a crucial vulnerability. We have taken the site down and will be working on patching PHP. It won't address the bot problem, but at least it will address the security issue.
This post will be updated once PHP is patched.
