We are investigating inbound email delays for some customers on Pod 6. More information to follow.
During this incident, ticket creation via E-mail was delayed for up to 40 minutes in Pod 6. An email loop caused an abnormally large email chain that delayed incoming tickets by email for customers on Pod 6. To resolve the incident, we emptied the mail queues into a temporary folder. We then introduced the mail in the temporary folder back into the mail processing queue at a slower rate while monitoring its performance watching for timeouts and queue backups. To prevent this from happening in the future, we are deploying code to prevent mail loops on our email servers.
