Yep, Google App Engine ran out of quota while I was asleep.
I have many GAE apps and when you enable billing, each app puts I think a $2 weekly charge on your card. To avoid spamming my books with dozens of tiny charges I turned off the billing for less popular ones like my blog. D'oh.
Additionally I had commented out memcache in the blog for some reason. Free quota would have been enough if it wasn't for that mistake.
