On Wednesday, February 19th, 2020 at approximately 15:49 UTC, Clients in the AE2 and AW zones started to experience email delays. These delays were due to the need to take some mail cluster members down in order to increase CPU resources. Unfortunately, this caused a higher than normal load on the mail cluster resources which resulted in the delays experienced by the customers. After the increase in CPU resources, email processing was caught up by 16:30 UTC. While pre-deployment estimates indicated that we would not be resource-constrained in this instance, in the future, we will over-provision mail hosts in the mail cluster in order to avoid low-resource situations in that infrastructure tier.
