Yeah, sorry for the vague description. That's the site I was thinking
about, thanks.

I don't have good success with lookups though, they tend to fail all

 "The query processing server could not be reached."

or

 "The server did not return any data. The server status is 201 Okay."

Is this typically a reliable source of information?
