Facebook pushed an update to their code that manages cookies, that had a rather severe bug in it that resulted in a large flood of requests to their database servers. To deal with this load, they had to prevent all writes and then slowly allow people back on.

I saw the writeup for it last night but cannot seem to find it now! Grrr. Did I dream it?
