While hard to solve in general, some of this is quite easy if you can
make a few assumptions.  Most server or VM farms can be scaled up or
down based on overall load, so I think these would be prime candidates
for this "servers come and go" scenario -- and they all have in-band and
sometimes out-of-band monitoring that you can tap into in various ways.

Just make it the responsibility of the user that each server in the list
given to parallel is actually reachable, don't second-guess the user.
That list may actually be something that the user just gets from
somewhere else, so you should perhaps be flexible with the expected
format.
