Interesting read. Could you blog about the math/techniques/algorithms you used to determine the best fiber paths?

Consider writing a SIGCOMM paper about it!!

We had to RFP each link, meaning we reached out to every fiber/wave vendor that was present in the data centers we wanted to be in that we could find, and had them submit routes with latency data. Then we tested to verify their data. It is really manual unfortunately.
