The name resolves OK. Here is a traceroute below. The first group of
hops pops up quickly. Sometimes it gets through 17 or 18 hops before it
times out. I get similar results from a machine I have at home on Comcast.
The script on our server posts a few fields to the recaptcha.net server
via http and gets a response code back. Fairly simple stuff. Nothing
that a firewall is blocking.
