and I also would ask.. what's the cost/risk here? 'We' lost at best
~1day for some folks in the outage, nothing global and nothing
earth-shattering... This has happened (this sort of thing) 1 time in
how many years? Expending $$ and time and people to go 'put padlocks
on manhole covers' seems like spending in the wrong place...
(yes, I agree also that simply dropping into a manhole with an
axe/hacksaw is pretty simple to do, it's also just about impossible to
realisitcally protect against)
