Your Primary Region Is Down. Fail Over Now?
The primary region is degraded. A teammate wants to flip DNS to the standby immediately. Defend whether and how you fail over.
the decision you defend
Your primary cloud region is having a major outage and your app is degraded. You have a standby in another region with an async database replica. A teammate says just flip DNS to the standby right now. Do you fail over, and how?
the situation
Your primary cloud region is in a major outage. The app is timing out and erroring for users. You maintain a warm standby in a second region backed by an asynchronous database replica.
context
The primary is degraded but it is not clear it is fully dead - parts of it may still be reachable and writable. The async replica is some seconds behind. A teammate wants to immediately update DNS to send all traffic to the standby region.
