Unfortunate but very true.... seen that many of times where a "special engineering" fee has been charged specifically to carry a circuit in a diverse manner (or even reasonably diverse).  Then it breaks and the excuses start as to why it was never done as promised - then a couple of years later it breaks and nobody has paperwork that shows it was *ever* supposed to be diverse in the first place....

Off hand, I wouldn't expect a carrier to do any special engineering on
a BRI -- can you even *order* a BRI these days?  :-)

As old NANOG hands know, though, it doesn't matter *what* you ask for,
few-to-no carriers properly manage physical diversity requests properly
over the long haul, anyway, and the only way to do it yourself often
requires that you ask the carrier for records they won't give you.

Regularly.  Like, monthly.

Even if you're paying them extra for the diversity.
