The unified Webex, fully redundant data center pair in the European Union (EU) supports all Webex workloads including Webex Calling. It is primarily aimed at our EU based customers but also available to EMEA customers.
Benefits of the EU Webex unified data center:
Designed to provide EU data sovereignty to customers who want it.
Customers hosted in the EU data center for all Webex workloads, will have data that resides in that data center pair in the EU.
Pre-Brexit, Webex Calling has offered hosting in the EU through a data center pair that resides in part in the UK and in part in the EU. That data center pair remains state-of-the-art, continues to serve the customers that are hosted in it, and is available to new customers.
The data center assignment for the new Webex Calling customers is a one-time, “hard” choice based on the country selection. The provisioning partner selects the data center assignment during the initial creation of the Customer Tenant for Webex Calling.
For all partners, the data center assignment for new Webex Calling customers starting August 2022 is as follows:
If the selection is any EMEA country (including any EU country), apart from the UK or Northern Ireland, then the new customer is assigned to the new data center pair in the EU.
If the selection is the UK or Northern Ireland, then the customer is hosted in the pre-existing data center pair that resides in part in the UK.
Partner organizations who require a different behavior by default, such as creating all customers by default in the pre-existing data center pair that resides in part in the UK, must contact the Partner Help Desk.
Data center assignment in Webex Calling is independent of data center assignment for the purpose of Webex. When a customer is initially created, they are first created in Webex, where shared services such as Identity reside. Refer to Administration - Data Residency in Webex for data center assignment for new Webex customers.
After the customer is created in Webex, they are assigned to a data center for the purpose of Webex Calling based on the above criteria.
Existing Webex Calling customers in EMEA, including EU and UK, are generally hosted in the pre-existing data center pair that resides in part in the UK.
There is currently no plan in place to proactively migrate these customers to the new data center pair in the EU. Data center migration is service impacting and generally not required, nor desirable, for most customers.
Existing EU customers, who require it, may be reactively migrated. These customers should contact Cisco support for assistance.
