Done. Things should be back to normal.

Probably just overloaded. I've seen this happen on occasion.

The site is under almost constant attack - spam attempts, attempts to create fake accounts, more or less systematic probes for SQL injections or other know vulnerabilities. Sometimes one of those overloads the site. The sheer amount of non-hostile bots indexing the site doesn't exactly help (why does every company have to run its own web crawler these days?).

Anyway, that has been the reality of the web for the last couple of years and Geeklog shouldn't just stumble over something like that so easily.

We could have a race condition in the cache refresh logic, for example. Could 2 requests trigger it at the same time, overwriting each other? Or something like that?
