"re-evaluating how best we can integrate".
For now fans who want to wag chins in any official channel will need to turn to Facebook (yuck) and Twitter (eww), "where it's business as usual." The Codemasters Blog possibly affected too.
It's unknown if the blog will remain offline or if Codemasters are making additional efforts to bring it back up.
"Our current forum supplier contract has come to an end, and we are re-evaluating how best we can integrate our community platform and channels with other online services such as RaceNet. Until then, please keep in touch with us via Facebook / Twitter where it’s business as usual," Codemasters in lieu of community chatter.
