I am in Thornhill, just north of Toronto. A couple of days ago I started receiving the "channel not available" message for HBOC2 on 303, 314 and 552. The same on my two boxes even after reboots. I work in downtown Toronto and it works normally there. I called in to tech support and they said my signal levels were good but they did see an issue and said they would get maintenance on it. The next day I got an email saying "We’re unable to identify an issue at this time". Anyone else north of the city having trouble with this channel?
