Even when you have control over both endpoints, months of uninterrupted service will be punctuated with weeks of playing hide and seek with the Firewall. BTDT.

The problem is when you have a global endpoint that Chinese customers want to access. What do you do then? You either have to figure out how close you can get your services to China and hope and pray they don't whack your traffic one day, or take the bigger risk of deploying your endpoint in China. Either is fraught, but if you want to service that population...

And remember, no multicast traffic in China...
