What is the crappiest network build you've ever seen? [closed]

Question

This is only about networks you have seen personaly, not heared from others or seen on pictures at the web.

• Cables hanging from the ceiling lamps?
• Cables going trough culverts and other tubes?
• Switches and other equipment in the cleaner's closet?
• Cleaning lady's rags drying hanging from the cables?
• Key to the main node door possesed only by the janitor (or other non-tech and completely non-network-related guy)?
• Switches powered by foreign power adapters (cheaper and providing non-specified voltage or amperage)?

All of this was in my old dormitory. Tell us about your bad experience.

I used to have a few others bookmarked for shock value...

Answer 2

I've seen a datacentre that used to flood regularly. Management decided it was too difficult to re-build the facility, so they ran all power overhead instead and put a drain underneath the floor.

The dehumidifiers get a workout whenever it rains, but I suppose the water would augment the cold, dry under-floor air conditioning as the air becomes saturated: underfloor swamp/evap cooler, who'da thunk it.
