Read-Only Mode

Read-Only Mode

Access to your data at a moment’s notice—even during our planned maintenance windows. To minimize interruption to your business, Salesforce gives users read-only access during splits, instance migrations, instance switches, pre-scripts, and certain other maintenance events.

What to Expect in Read-Only Mode

When Salesforce is in read-only mode, you can navigate within the application and view and report on your business data. Activity reminders don’t occur, and Recent Items lists don’t update. Login history is still recorded for compliance purposes, but it isn’t reflected in your organization until a few minutes after the organization exits read-only mode.

During read-only mode, you can’t:

  • Add, edit, or delete data
  • Perform any actions in Salesforce that modify your Salesforce data. For example:
    • Post on Chatter
    • Use Chat
    • Refresh dashboards
    • Perform API write or edit actions
    • Perform bulk API read actions
    • Save new or edited reports
  • Access the forecasts page

When your organization is in read-only mode, users see a banner at the top of their browser window:

When to Expect Read-Only Mode

The maintenance schedule posted on trust.salesforce.com indicates whether each upcoming maintenance window includes read-only access. Planned maintenance windows vary in length depending on the level of maintenance needed. In addition, when users are notified two weeks before a planned maintenance window, the notification specifies whether the maintenance includes read-only access.

If you’d like to see how your organization works in read-only mode, contact Salesforce to have the testing option enabled in your sandbox organization.
