56. Cascading data center problems: In or around the spring of 2021, Twitter's primary data center began to experience problems from a runaway engineering process, requiring the company to move operations to other systems outside of this datacenter. But, the other systems could not handle these rapid changes and also began experiencing problems. Engineers flagged the catastrophic danger that all the data centers might go offline simultaneously. A couple months earlier in February, Mudge had flagged this precise risk to the Board because Twitter data centers were fragile, and Twitter lacked plans and processes to "cold boot." That meant that if all the centers went offline simultaneously, even briefly, Twitter was unsure if they could bring the service back up. Downtime estimates ranged from weeks of round-the-clock work, to permanent irreparable failure.
