Final status: We've identified that a section of infrastructure, responsible for email attribution and routing, unexpectedly became unresponsive and resulted in DNS lookup failing to resolve hostnames. Additionally, this DNS issue prevented user traffic from being directed as expected and resulted in mail flow delays. We've rerouted user traffic to alternate infrastructure which restored the mail flow delays and remediated impact.
