Generally no one but Mods and a few others (like little ol' me) read other people's post. From what I seen they just post on their own problem threads. So i don't think you will hear much from other users. Though if someone in OC is reading this, please post.
With that said, did you still want to troubleshoot? If so, please give some background on the issue? When those channels don't work, what happens? Very well may be some kind of outage, in which case I won't be any help, but if not, I will be happy to see if I can at least help isolate it. :-)
