          Spring ’26: Legacy Host Name Redirections Stop

          Spring ’26 deployment starts in January 2026 for production and demo orgs. In this release, Salesforce disables redirections for legacy (non-enhanced) host names in production orgs and demo orgs. With that enforcement, those redirections can’t be reenabled in any org.

          Note
          Note The end of redirections for legacy (non-enhanced) host names is enforced through a release update. Release updates are completed gradually after the major release. Usually the enforcement processes finishes within a few hours after you get the release, but it can take up to 24 hours. To control the timing of when legacy host name redirections stop in your production or demo org, disable legacy host name redirections before your org gets Spring ’26.

          Summer ’26: Testing Available for Incorrect Instanced URLs in API Traffic

          Summer ’26 deployment starts in April 2026 for sandboxes and in May 2026 for production orgs. Starting June 19, 2026, you can test the end of support for instanced URLs in API traffic. In Setup, find and select My Domain, then enable Block API traffic that uses an incorrect instanced URL in the Redirections section of the My Domain page in Setup.

          Warning
          Warning If you enable “Block API traffic that uses an incorrect instanced URL” before the related known issue is resolved, SOAP login URLs via Visualforce pages can return a 400 Bad Request error. Salesforce plans to deploy a fix for that issue June 16–18, 2026, so we recommend that you test this change after June 18, 2026.

          For more information, see End-of-Support Schedule for Incorrect Instanced URLs in API Traffic.

          Winter ’27: Support Ends for Incorrect Instanced URLs in API Traffic

          Winter ’27 deployment starts in August 2026 for sandboxes and in Septembmer 2026 for production orgs. Shortly after your org gets this release, API traffic that uses an incorrect instanced URL is no longer supported.

          This change is enforced on a rolling basis. For specific dates, see End-of-Support Schedule for Incorrect Instanced URLs in API Traffic.

          To control the timing of when API traffic that uses an incorrect instanced URL stops working in your org, disable that traffic before that change is enforced in your org. Disable the Block API traffic that uses an incorrect instanced URL My Domain setting.
