We're experiencing some temporary downtime at the moment. And, for once, it's not something stupid I did.
All App Engine sites appear to be choking on webapp.util and django.util imports at the moment. Which, if you are unfamiliar, is pretty much every App Engine site ever.
I'm sure Google is rushing to fix whatever broke, but I have no idea what it is or how long it will take. I'll keep you posted if I learn anything else. Sorry for the inconvenience-- this one's out of our control.
Thanks,
Paddy Foran
