I am skeptical of the 6 weeks. There is no business reason that I can see for taking the forum down - it worked most of the time and as far as I can determine consumed little in the way of TF staff resources - it wasn't monitored (according to TF staff and I don't recall seeing any feedback from them) and, being pretty bog standard forum software, should not have required much maintenance. There could be a technical justification for a short break (as the service is clearly not deemed business critical) such as change of server or change of forum software, but there's no way this should take 6 weeks so it should be up sooner. But the decision might be political - in which case it might never come back.
