Bitdefender GravityZone experienced slow portal performance on its cloud service, which later expanded to affect email processing. A fix was implemented, though emails sent during the degradation window may have received temporary 450 rejection codes, causing potential delivery delays dependent on sender retry schedules. The incident lasted approximately 1.3 hours before changes stabilized and normal email flow was confirmed.

Changes have remained stable and email latency is normal. Thank you for your patience.
We have implemented a fix and are currently monitoring performance. Email is now flowing, however, emails received during the performance degradation window may have received a 450 rejection message.
This 450 code informs senders to temporarily back off and retry delivery at a later time. As a result, there may be delay receiving certain emails. Please note that the time frame for a retry is decided by the sender's infrastructure and is not controlled by Extended Email Security.
We are investigating slow performance of the portal on our cloud service. Email processing is not impacted.
