054: We're So Quacked!
At 3:30 AM the day before Thanksgiving, Ben received an emergency page about a failing API end-point. Rushing to his desk, groggy-eyed and in various states of undress, he jumped into the
#incident channel on Slack to see what was happening. What unfolded over the next 30-hours was the manifestation of Ben's worst nightmare. The moment he had been dreading for the last 4-years had finally come to pass: two of his database columns had run out of storage space! Using feature flags, emergency hot-fixes, shadow tables, and a database migration being performed over a transient and unstable terminal session, he and his team somehow made it through to the other side just in time to enjoy Thanksgiving turkey and pumpkin pie!
