Is your experience that when routes reconverge, they still select the same end POP they did prior to the flap?

Assuming the end POP is still reachable along another regional route, I believe all the data I've seen shows that the client almost always hits the same destination they did before the flap.

A POP or edge location is a server (or multiple) that the user traffic is being routed to, hopefully close to the user. A CDN consists of multiple POPs, one in each region, with intelligent traffic routing added (as described in the article).
