Accessing reCAPTCHA

We use reCAPTCHA for some customers. Around Wed of last week, no answers were accepted as correct. We have traced the issue to a failure in communication between the webserver and the recaptcha service. Is there anything on Jodo’s end that would have changed to prevent this?

More info:
http://www.recaptcha.net/

test harness: http://www.cordua.com/area51/rc.cfm

server that can’t be reached is api-verify.recaptcha.net

Possible Cause: ??? http://wiki.recaptcha.net/index.php/Firewalls_and_reCAPTCHA ???

Other Possible Cause: We use cfhttp/cfhttpparam to talk to the recaptcha server ???

We havent changed anything that would cause this, we added the extra logging, but it doesnt prohibit anything,

Is the request timing-out, or is there some kind of HTTP Error response from their server?

I have been using without problems from jodo. Maybe it s machine specific?
