We will be performing Zoom Phone maintenance on our Europe (Amsterdam) data center on November 6, 2021.

Zoom Phone users registered to the Amsterdam data center will be automatically registered in an alternative datacenter starting at 9:00PM CEST on November 6, 2021 (12:00PM PDT on November 5). During the maintenance window, a brief disconnection may be experienced and notifications may be missed. If you get disconnected, the system will attempt to reconnect you automatically. If you are a BYOC (Bring Your Own Carrier) customer, please ensure that your Session Border Controller (SBC) is configured with alternate routing to Zoom’s Frankfurt data center in addition to the Amsterdam data center. During the maintenance window, connectivity to Zoom’s Amsterdam data center will be blocked which will force calls from the Session Border Controller (SBC) to failover to Zoom’s Frankfurt data center. Traffic will continue to be routed through the Zoom Amsterdam data center once the maintenance is completed.

We will be performing maintenance on the Billing tab of our web portal on November 13, 2021.

From 4:00PM to 10:00PM PDT on November 13, existing customers will not be able to access the Billing tab of our web portal and will not be able to subscribe to new services, pay invoices, or update their payment methods.

Additionally, during the maintenance window, new customers attempting to sign up for paid Zoom services will be taken to a web page about the maintenance, offering them a free trial of the Zoom meetings service. They will be able to return to the Billing tab of the web portal to upgrade to the paid service after the maintenance is complete and before the trial expires.
