1Password contacting undocumented domain

1Password for Mac just reached out to the FQDN app-updates-internal.agilebits.com.

That domain isn't in your app's Internet Access Policy, so there's no documented reason why it would be contacting that endpoint.

There's an entry for app-updates.agilebits.com, with the description:

1Password connects to its update server to check for updates. If you deny this connection, you won't be notified about updates to 1Password, including security updates.

Is it intended for the production release to contact app-updates-internal.agilebits.com?

1Password for Mac 8.10.58 (81058041)
I've updated to 8.10.60, but I don't see anything in the release notes about this in .58 or .60.
