Symantec, a division of Broadcom, is performing maintenance of EMEA Email Quarantine beginning April 23, 2022, starting at 3:30 UTC, for a duration of 8 hours.
During the maintenance period, Symantec EMEA Email Quarantine Portal will not be available and emails directed to the quarantine will be queued. These emails will be delivered to the quarantine after the maintenance has been completed. Quarantine summary notifications/digest emails will then be resumed.
Email Security scanning and mail traffic delivery will not be interrupted and all other aspects of our services are expected to function as normal.
Start: April 23, 2022, at 3:30 UTC
End: April 23, 2022, at 11:30 UTC

REASON FOR CHANGE
The firmware upgrade is required in order to enhance the overall operational experience and availability of the Network Core. This will mitigate any known security risks and enhance performance.
* Upgrade of GM-2-1 to firmware 4.27.5
* Upgrade of GM-2-2 to firmware 4.27.5
* Upgrade of GM-1-1 to firmware 4.27.5
* Upgrade of GM-1-2 to firmware 4.27.5
Once stable and in sync, we will then proceed with the following:
* Upgrade of GM-2-1 to firmware 4.30.8
* Upgrade of GM-2-2 to firmware 4.30.8
* Upgrade of GM-1-1 to firmware 4.30.8
* Upgrade of GM-1-2 to firmware 4.30.8
Customers may experience connection disruption while the switches re-calculate internal and external routing.
The Core Switches and architecture are designed to facilitate non-disruptive changes. With the switch firmware upgrades and reboot of the switches, the connections may trigger a BGP and internal route re-calculation. Persistent connections will automatically be re-established.
