Order of launching sites on a multisite

The “main site” of a network on a WordPress multisite environment is typically the first site (ID 1), and will be listed first in the Network Admin Sites screen.

The main site should be used for administrative purposes only: with a default theme activated, no content added, and access to the site restricted by Maintenance Mode.

The main site must be launched with a custom, non-convenience domain (something other than *.go-vip.net) before any other site on the multisite can launch.

All new sites added to a multisite network will initially exist as subdirectories of the main site’s domain. It can therefore be useful to have a custom domain assigned to the main site (ID 1) for branding purposes, such as admin.example.com or vip.example.com.
