@mattpierce -- nothing has changed with any connections!
Although you have not changed anything, it is possible that something, such as a coaxial-splitter, has failed.
As an experiment, if there is a splitter between your coaxial wall-outlet and your equipment, e.g., one output to TV and one output to cable-modem, bypass the splitter, and connect the TV box directly to the wall-outlet.
Did a tree fall onto the coaxial-cable between your residence and the nearest telephone-pole, breaking the cable?
Any lightning in your neighbourhood that may have "fried" some Shaw equipment?
See the Shaw "outages" page, to see if there was a problem in your region/neighbourhood.
What time did the outage start? end?
Early this morning -- about 1 AM Pacific -- I lost all Internet connectivity. It was back to normal, when I checked at 7 AM.
