This was due to a DB mistakenly being depooled. On Monday the intention was 1 dB would be depooled for maintenance, accidently 2 were depooled. This lead to dB stress during peak times (UTC evening). The same thing happened on Tuesday. We figure out exactly what was wrong Tuesday evening and rebalanced the pooled DBs slightly to shift some load around and to avoid waking the DBAs up. Wednesday morning the mistakenly depooled dB was re pooled.
