How will the clients change their configs whilst the server is down?

If the main server goes down, the clients will use their local copies of
the inputs.  The inputs won't change because the server can't be
contacted, unless you have some out-of-band system changing the inputs
anyway, in which case you've got problems regardless of whether the
server is up or not.

When the main server comes back up, either the local copies will be up
to date or the server will be newer, and they'll update and continue on
as expected.
