Most private endpoint outages are not “networking problems.” They are ownership problems.

You can have a clean hub-and-spoke design, strict firewall rules, and perfect private endpoints… and still break apps because nobody can answer one basic question: who owns DNS for private connectivity?

When DNS ownership is fuzzy, teams create their own zones, link them to whatever VNets they touch, and ship changes without a test plan. Everything works until one new VNet, one new private endpoint, or one new conditional forwarder changes name resolution. Then you get the classic symptoms: timeouts, TLS errors, random “it works on my VNet,” and a war room full of people staring at peering diagrams.
