Freezing slowed down for a day, but back as previously stated. It begin approximately 5:00 pm PST (8:00 EST) and becomes unwatchable within a very short time. The freezing stops approximately 11 pm PST (2 pm EST).
At this point anyone looking to sign up, I would suggest waiting until the issue is resolved as the channels are unwatchable, as well as the Video Library. From what I can see here, it looks like load capacity issues and possible redundancy because of load.
If you are looking to add the service, definitely hold off until this is resolved, as there is no need to get frustrated.
