It's just not as interesting or hard to troubleshoot as a poorly made
patch cable that's had one conductor go open, only goes open when the wire
is tugged a certain direction, nicked wires shorting, a switch port with
its RX side burned out, an RJ45 plug who's mistreated tab no longer works,
and though it looks inserted in the port, it's really just kind of hanging
there not making full/good contact, etc.
I would hope in any data center, "stealing pairs" doesn't happen as much
as any of the above or taking pairs the tech genuinely thought were dead.
