Like, I know they called it “The Astonishing, Unfailing, Bell System” but if they had an outage somewhere did they actually have an infrastructure of “canary phones” and such to tell in real time? (As in, they’d know even if service was restored in an hour) Not trying to snark, I legit got nerdsniped by this comment.
