When my former employer, Frontier Communications, built out their Congress Street Boston switch site, they had Verizon install a 25-pair cable that ran from the phone/storage room out to a spot underneath the switch room floor. This was intended to be used to bring dial tone out for dialup modems.
At one point I got so sick and tired of dealing with the Krone blocks that Verizon used, I swapped them out for 66 blocks.
Then, when Level(3) bought us out and I moved to their Cambridge MA landing, I found that Verizon had installed a rack mounted frame full of Krones for Level(3) to wire to in order to bring dial tone into the colo cages as needed.
Many of the blocks had broken hinges with the covers dangling...and...the wiring looked atrocious.
Verizon could have done a better job if it had installed 66 blocks instead.
