Datto Drive instances are tied together by your subdomain. The subdomain is the portion of the URL that comes before
You can quickly check if your desired subdomain is available: Navigate to subdomain.dattodrive.com, where subdomain is your desired subdomain. In this example, I attempted to navigate to abctest.dattodrive.com, which came back with a 404 error. This indicates that the subdomain is currently available because it is currently not hosting an instance.
Another way to check is to sign up on our website https://dattodrive.com/. In the event the subdomain is taken, you will get a message indicating the status of the subdomain.
You can request access to the subdomain by clicking the link Click here to request access. This is helpful in case other employees of your organization have already created a Datto Drive instance for your organization.
