It happened a few weeks ago as well, but as it was a Sunday and vanished on Monday I figured you figured it out. May as well be a different cause this time - good luck with finding it.

I've seen this again a few times in the last few days - it would get stuck for an hour or two, and usually would work again when I remembered to come back. Didn't write down any times, though. I guess you got less patient users who'll inform you faster than I can :).
