Yeah, looks like regional redirect. For me redirects to .lv which returns SERVER NOT FOUND error. Probably should have been PIZZA NOT FOUND error or PIZZA UNDELIVERABLE.
Try long-pressing or right clicking the back button to get a menu of past locations. This used to be a visible and discoverabledrop down menu in most browsers but (insert rant about modern UI design here).
The cert loaded on pizzahut.ca is for shortener.secureserver.net. The cert for www.pizzahut.ca is good for *.pizzahut.ca, but they're just not loading it for pizzahut.ca. :/
