Static IP Address for customers.gitlab.com
@greg raised an excellent point related to the new Seat Link Service. Given what we know about usage ping, there will be some self-managed customers that have network restrictions that will prevent outbound requests unless the IP address is whitelisted. In order to support these customers, we need to provide these customers with a static IP address of the Subscription Portal (https://customers.gitlab.com).
@cmcfarland did some preliminary research for us and found that customers.gitlab.com uses a dynamic IP address.
Just from poking around, it seems like it's possible, but we might need to do it during a weekend since it's not an HA service and it's running in an old classic VM in azure.
