That's not our experience either. BGP is fine.

But it is the case that transit and peering connections are not stable (in the sense of going up and down randomly or suddenly experiencing high levels of packet loss) and active monitoring is a must.

Thank you to both of you, I've edited the article to clarify that point.

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.

What is POP?

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).
