I certainly see this as a challenge to compete with the breadth of the existing CDN networks.  Many cases it is just easier to outsource this function and capability.  I've found myself starting to lean in the direction of minimizing the problems that I need to debug/solve.  This usually results in a lower cost and more free time to deal with whatever else it is.

Building your Anycast/Mini-CDN infrastructure yourself is going to make it so you need to re-learn lessons that others have already learned.  Even if you were formerly at a CDN, I'm sure there is some black magic you were unaware of.

It sounds like you have a few servers and are just trying to do IPv6 "on the cheap" or similar to HE.  It may be worthwhile to avoid the tunneled infrastructure to yourself and use a carrier that has native.  There are numerous carriers with a global footprint that can do this for you.

I would be cautious about the complexity and your overall requirements of performing a solution like this.  Anycast is just a name for a technique, there is more to it than that to implement it.  (In the same way internal combustion engines have various levels of complexity - diesel, gasoline, E85, injectors, etc).
