Please be advised that we will be performing scheduled maintenance on the Email Security.cloud infrastructure. This migration will begin on May 14th, 2018 at 08:00 UTC and will be completed by June 15th, 2018 23:45 UTC. In order to avoid any service disruption, it is critical to ensure you are allowing Symantec.Cloud IP ranges listed here
for successful traffic delivery.
Please be assured this work is intended for your benefit and is part of our ever-advancing plans for improving the reliability of the service and customer experience.
