Here’s how to get status information using your My Domain name.

  1. Go to Trust Status.
    The Status & Maintenance page shows the status for each org instance.
  2. To view your org instance, enter your domain name in the search bar.
    Don’t enter the complete URL. For example, if your org’s login URL is https://example.my.salesforce.com, use example.
  3. Under My Domains, select your instance.
If you don’t want to use your My Domain name, you can find your instance on the Company Information Setup page. From Setup, in the Quick Find box, enter Company Information, and then select Company Information. The Instance field contains your org’s Salesforce instance.
