Our engineers have determined the root cause of this outage was a spike in traffic between internal APIs, which caused cyclic crashes between two services within Flow as one repeatedly overwhelmed the other. We will be prioritizing work to distribute our API's boot-time request volume to prevent this manor of failure in the future.
