Traceroute to forums.freebsd.org dies at the destination network. Happens from my home DSL as well as all other places I've checked. Here's the traceroute from freefall:

This appears to have been resolved. Please test.

forums.freebsd.org responds on IPv6 again. I don't have access to the Project's internal sysadmin tools to ascertain whether proper monitoring has been added to halt the reliance on end user reports like this one.
