: Our on-call engineers were paged for network monitoring failures, and started investigating immediately 09:15 UTC : We started seeing partial recovery from users, and continued our investigations into the root cause At 09:08 UTC, we started seeing database-related errors across all instances of our network control plane that mentioned read replica had to sync with the primary instance. As part of this work, we’re going to create regional control planes instead of a global control plane, which will help us contain the blast radius of control plane failures, and allow us to mitigate any single-region failure by failing over route information lookup to other regions.
