Messages from a Team Interrobang admin:

7 AM – Site appears to be functioning slowly.  Unsure of problem, investigating, can anyone help?
10 AM – Site now appears to be down.  Looking into causes, tech support for hosting contacted.  Could use some guidance.
1 PM – Fixed.

I woke up at 1:30 PM to a perfectly functioning site.

This is why I sleep in on Sundays.
