Stabilize URLs for Visualforce, Experience Builder, Site.com Studio, and Content Files (Previously Released Critical Update)

We’re removing the instance names from Visualforce, Experience Builder, Site.com Studio, and content file URLs. An instance name identifies where your Salesforce org is hosted. Instanceless domains are cleaner and easier for users to remember. This critical update applies to orgs that have a deployed My Domain. After this update, a URL that includes the instance name, such as a bookmark, automatically redirects to the new hostname. This critical update was first made available in Spring ’18.

Where: This change applies to Lightning Experience and Salesforce Classic in Contact Manager, Group, Professional, Enterprise, Performance, Unlimited, and Developer editions.

When: The critical update is activated automatically in production orgs on July 11, 2020 and in sandbox orgs when they are created or refreshed.

Why: When we remove the instance name from your URLs, your hostnames change. For example:

  • mydomain--c.visualforce.com replaces mydomain--c.na1.visual.force.com
  • mydomain--c.documentforce.com replaces mydomain--c.na1.content.force.com

All *.content.force.com URLs are replaced with *.documentforce.com.

How: We recommend that you test this update in a sandbox to ensure that the new URLs work with firewalls and proxy servers in the network path between your users and Salesforce. Firewalls and proxy servers that filter by hostname must also trust the following:
  • *.visualforce.com
  • *.documentforce.com
  • *.salesforce-communities.com

To activate this critical update, from Setup, enter Critical Updates in the Quick Find Box and select Critical Updates. For Remove Instance Names from URLs for Visualforce, Experience Builder, Site.com Studio, and Content Files, click Activate.

Note

This update can log out users who are accessing Visualforce, Experience Builder, Site.com Studio, and content file URLs. To minimize disruption, consider activating this critical update during off-peak hours.
