sorry for the delayed response guys.

It may not always be the case, but I think it is fair to assume that a company which operates datacentres in diverse locales will have negotiated reasonably optimal peering agreements.

exactly! Also, don't you think its highly unlikely that all of the providers in that country will route data via sub-optimal routes. And if that's true, we can always ask the provider for special arrangements?

If you can afford a few million dollars per year for networking, quite a few options become available.

Can you please elaborate on this? Like exactly what options do I have available and how will they be beneficial as compared to the current arrangement?

I am also in the process of getting a PoC done in next few weeks to get answers to this question but would appreciate your insights too :)
