Ex-Telco Engineer here. The Power Rooms of your local Telco are amazing places. Ever wonder why, when power goes out for extended periods, that your non-portable phone still works?? Because they do not actually work directly thru the Commercial AC utility. They power all of the switching gear, even the air conditioners, with Batteries, just like a UPS box. When the AC power goes down, they are already on battery: no pulse/no jump/no dropped calls. When the batteries start to go down, they have a diesel generator outside with a buried fuel tank that fires up to charge the batteries. When the fuel is gone, you are back to smoke signals.
Just trivia for those interested, and that is why your DSL still worked.
