Here's some more information about what happened, and what's being done about it:
Best Practical Solutions -- SECURITY ADVISORY.
At this point, we don't suspect that anything malicious was done to http://rt.cpan.org.
I'll try to post another reply when & if I have more information to offer, or if I get an ETA on its return.
We apologize for any inconvenience.
