       The mysterious network problem that cost me most of yesterday turns out to have been caused by someone helpfully plugging in a network cable that wasn't meant to be plugged in.This is the second time I've found a tricky network problem to have such a cause.I think there's some sort of cognitive illusion that afflicts people who don't regularly mess with networks, where they would never _unplug_ a random cable without worrying it might cause problems, but somehow it doesn't occur to them that _plugging in_ a random cable could also cause problems.
