Question
Users intermittently see stale data — something they just wrote isn't there on the next read. You use read replicas. What's happening and what do you do?

Stop the bleeding first (mitigate), then form hypotheses from real signals. Separate root cause from symptom, communicate status as you go, and close with what prevents a repeat.
