XF 1.3 ReCaptcha Error (Name or service not known)

Awhile back, I posted a support thread in regards to ReCaptcha and Gravatar failing to connect to their respective services. As it turns out, it was just a hosting issue. Now, I have another error, but this one only pertains to ReCaptcha.

Unable to Connect to tcp://api-verify.recaptcha.net:80. Error #0: php_network_getaddresses: getaddrinfo failed: Name or service not known

Today at 2:25 AM - library/Zend/Http/Client/Adapter/Socket.php:235
Is this something I should be worried about?

My host reported that the server my site is hosted on can connect to api-verify.recaptcha.net using port 80 without a problem, showing me some trace routes through the server. He also provided me with a few php tests:

http://www4.coreisp.net/test80.php <-- This shows that the server can communicate through port 80 fine.
http://www4.coreisp.net/test81.php <-- This shows that port 81 is closed (after a couple minutes), which is normal.

I've also noticed that Gravatar cannot communicate through port 80, either. Any suggestions?

Are you running on a VPS/dedi server? If so, check your resolv.conf and see what DNS servers are listed. I ALWAYS use and in addition to what it configures by default (and place them at the top of the list).

I had a similar issue not to long ago on one of my VPS's and it was driving me nuts till I compared the resolv.conf of it to one of my VPS's that worked) and realized that was one thing I had forgotten to do (and looking over my checklist noticed I had skipped it).
