Planned Maintenance for Email Threat Isolation Customers – October 17, 2021

Sunday, 17 October 2 hours

The scheduled maintenance has been completed.


Scheduled maintenance is currently in progress. We will provide updates as necessary.


Clarification on the service disruption

From an end user perspective, when interacting with a rewritten URL or an isolated file that needs Isolation processing, they will be met with an error. We ask users to wait until the end of the maintenance window and then re-engage with the respective rewritten URL or isolated file resources again.


On October 17, 2021, we will perform service-wide maintenance on the Threat Isolation Service for Email Security Service customers.

The maintenance event will start at 14:00 UTC and continue until 16:00 UTC.

Impact Only Email Security Service customers who use the Threat Isolation add-on will be impacted. Customers should expect service disruption of up to 30 minutes during the maintenance window. All other aspects of our services are expected to function as normal.

Customer Action No action is required.
