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 new Webex Calling customers is based on the country in which the first location created for Webex Calling (in the Calling tab in Control Hub) is located.

  • If the first location created is in any EMEA country, apart from the UK, then a new customer will be assigned to the new data center pair in the EU. In particular, if the first calling location is in an EU country (post-Brexit), the customer will be hosted in the new data center pair in the EU.

  • If the first calling location created is in the UK (including Northern Ireland), then the customer will be hosted in the pre-existing data center pair that resides in part in the UK.


Data center assignment for the purpose of 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, from the Calling tab in Control Hub, they will be assigned to a data center for the purpose of Webex Calling based on the country of their first calling location.

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, will be reactively migrated. These customers should contact Cisco support for assistance.
