Looks like API module flaked out on me. It had finished indexing the Domain module suite, and then it wiped everything out.
I will need to take some time to debug, but may not get a chance for a while. My apologies.

Anyway, here are the modules that will be documented here:
With any luck, these will all be up and running by the end of the week.
