Data residency for Slack

Data residency for Slack allows global teams to choose the region where certain types of data at rest are stored. You can contact our sales team to set up data residency for your organisation. If you’re using the free version of Slack or the Standard subscription, you’ll need to upgrade to the Plus subscription first.

Before you get started, here’s what you should know:

  • We currently offer data storage in Frankfurt, Germany and Paris, France.
  • Customers must store all Slack data in a single region.
  • Customer data stored in Frankfurt is backed up in Paris, France.
  • Customer data stored in Paris is backed up in Frankfurt, Germany.

Note: The data residency feature does not change any aspects of Slack other than the data storage location. Slack will continue to store and process all other categories of data in accordance with your written agreement for Slack services and Slack’s privacy policy.

How data residency for Slack works

Customer data

The following categories of customer data will be stored at rest in a data centre within the customer’s selected region as of the date data residency is enabled:

  • Messages, posts and snippets
  • Files (e.g. images, docs) uploaded to the service
  • Search index of customer data
  • App- or bot-generated messages and files

Other categories of customer data, such as user profile information and channel names, channel topics and channel descriptions, may be delayed or unavailable for storage in the data residency region.

Other data

The following categories of data may be processed and stored in regions outside of the customer’s data region:

  • Workspace and channel membership information
  • Data used to measure seat count, usage and revenue
  • Data used for analytics and to measure quality of service, e.g. sanitised logs
  • IDs generated by Slack on behalf of the customer

Data migration

If a new workspace or Enterprise Grid org is set up in a data residency region, customer data will be stored in the selected region starting on the date the workspace or org is created.

For existing customers wishing to enable data residency, customer data can be migrated to a selected data region at any time. When a workspace or Enterprise Grid’s data is migrated, all new user data will start residing in this region. However, old data will continue to live in the United States. Over time, Slack will migrate the data stored in the US to the customer’s selected data region.

Shared channels

If two organisations connected by a shared channel are both in the same data region, all of their customer data will remain in that data region as well. If the organisations are located in different data regions, the following will happen:

  • Each organisation’s messages will live in their respective data regions.
  • The search index for the shared channel will live in both regions.
  • If the shared channel is disconnected, both organisations will get a copy of the other party’s previously shared data.

Note: Enterprise key management (EKM) is not currently integrated with data residency, but we may offer this capability in the future.
