Well it's back now.
Down maybe 5 minutes.
Somebody tripped over the power cable and unplugged it from the wall at the up-link.
Still a few intermittent macro blocking and black screens.
Doesn't Dish have another satellite at 61.5 as an in-orbit spare? Dish could have been moving channels from one satellite to the other, or simply doing routine maintenance shuffling channels from one transponder to another on the existing satellite. If we still had uplink reports, that would have given us some indication of what was actually going on when the outage occurred.
