That's a great example. Thank you James for sharing. I have done so many "GROUND TRUTH" visits where randomly selected certain physical points to validate physical diversity. Have seen several places where dual risers in the building were present or multiple building entries were available but not used. Ground truth events are certainly important and can be eye opening. It does not necessarily scale as you can't really walk all the fiber A-Z everywhere.. i know. On Tue, Dec 18, 2018 at 6:49 AM James Breeden <James () arenalgroup co> wrote:
I can't stress enough the importance of controlling your own route and even cable diversity. Require KMZs of the routes for any services you take (especially single path Wave type services). Put them in the contracts if you can. I've had at least 1 situation where we had vendor diversity and what was supposed to be route diversity- 3 separate waves coming south and southeast out of a datacenter to 3 separate cities. Imagine my surprise when we took a outage one day that severed all 3 circuits. Yes all 3 circuits, going to 3 separate cities, on 3 separate carrier/s DWDM platforms, all happened to show up in the same sheath of cable at one location that happened to experience backhoe fade. Was not a good day.... *James W.

I do and did care. I don’t want to put all my eggs in one basket. Do you care? Thankyou There are advantages and disadvantages to vendor diversity. As advantages, you won't be subject to complete loss of connection because of a single dispute or provisioning/control plane issue with that one vendor. You can also more easily pit vendors against each other for pricing if you are already vendor-diverse. As a disadvantage, not only does vendor diversity obviously not imply route diversity, but it will completely put the onus on you to ensure route diversity if you want it. With a single vendor, you can demand that your circuits have route diversity and, assuming you trust them, they have all the information they need to make that happen for you. -- Brandon Martin
