LinuxQuestions.org - post-review errors

When I try to post a review like so:

post-review

I get the following errors:

raise URLError(err)
urllib2.URLError: <urlopen error [Errno -2] Name or service not known>

How do I solve this, it was working normally before but then these errors started comingup.
