“Game day” was October 21. The election was still 17 days away, and this was a live action role playing (LARPing!) exercise that the campaign’s chief technology officer, Harper Reed, was inflicting on his team. “We worked through every possible disaster situation,” Reed said. “We did three actual all-day sessions of destroying everything we had built.”

Hatch was playing the role of dungeon master, calling out devilishly complex scenarios that were designed to test each and every piece of their system as they entered the exponential traffic-growth phase of the election. Mark Trammell, an engineer who Reed hired after he left Twitter, saw a couple game days. He said they reminded him of his time in the Navy. “You ran firefighting drills over and over and over, to make sure that you not just know what you’re doing,” he said, “but you’re calm because you know you can handle your shit.”
