We are investigating and issue that caused our MailFlow Monitoring to change our TimeZone to UTC. This is causing MailFlow monitors to report delays even though the do not exist. These are false positives, and our Team is issuing a fix as this is being typed. The behavior shows approximately 18000+ seconds in latency. We expect this to be resolved shortly. Thank you for your patience and understanding.
