Thanks for this. I've had physical diversity on my mind lately so this was
helpful.

(mostly joking... but still)
Academics face a severe challenge in gaining access to fiber maps since the industry classifies virtually everything as proprietary. If you know a better paper, please post it.

Undersea is a lot easier since cables pose safety threats. Any fishing organization will have maps of where the undersea cables are located.

I don't, which was part of why I was joking.
The ATIS final report on the National Diversity Assurance Iniative is decent. ATIS had access to proprietary carrier maps and personnel to

It could be summarized as "Circuit route diversity sucks." The only thing worse than circuit route diversity were the processes to assure diverse circuit orders stayed diverse.
No small feat when carriers re-groom circuits and don't bother to tell anyone, beyond *maybe* a cryptic notification regarding "maintenance on your service".
