[2019-01-13, 14:20 PDT] Mtpremiumus04 RDS failover.

Discussion created by Rudolf Gati Employee on Jan 13, 2019

The MySQL (RDS) server on mtpremiumus04 stack crashed. Automatic failover was triggered and service resumed to normal after a minute. Operation has engaged with AWS to investigate the root cause.

AWS support answer:

At 2019-01-13 20:22:38 UTC our internal monitoring system detected that the underlying host of your primary instance was not healthy and therefore initiated a failover to the secondary.
It has replaced the underlying host that was unhealthy.
