The environments that I've been in where the cabling has gone to hell after install did so for two reasons:
1. The network administrator is wearing multiple hats and doesn't have time (or can't afford downtime) to keep the cabling clean.
2. The cabling is run so tight that it's faster and easier to patch a fresh cable than cleanly re-route an existing cable.
While that cable plant is ..... something I can't describe using written words, there's nothing indicating that they're all cross overs.
Yeah I know, was just being funny because they chose all yellow. But I think the standard of yellow meaning cross over is something that died a painful death. I see yellow used all the time for non cross over. Heck, we even give yellow patch cords to our customers when they get DSL from us.
Speaking of wire messes, my rack aint the prettiest either. D: I plan to build a wooden enclosure of sorts so I can add some cable ducts and other cable management stuff as well as a pdu. Not in the budget now though.
And some hackery to detect AC failure and read battery voltage. (shares a single cat6 cable)
