Similarly for Noisebridge / Noisetor, we decided to host at a commercial
facility separate from our "production servers" both for
cost-per-bandwidth and separation-of-risk reasons.

I don't think it's very likely that cops would bust down a door at CMU
to sieze equipment under an ill-conceived investigation; having an
institution is quite helpful in getting the cops to actually do their
jobs and validate their suspicions.  (Unfortunately.)

In my case (and, I suspect, most of us "well paid techies"), I would be
back online with new hardware and a 4G modem a few hours after the cops
finished their smash-and-grab, so while losing the higher bandwidth of
the fixed line and the use of my hardware would be quite inconvenient,
it wouldn't be the end of the world.  It's important to have a
contingency plan for this case, though.
