I'm not sure if it had been there for a while and I just hadn't rebooted my modem or what, but after a 2 hour outage yesterday, I'm now rocking 3 upstream channels.
No change in speeds (not that I expected that anyway), but hopefully once they have deployed USCB we will maybe get speed plans with more upstream!--
