You might want to use the 'offline_mode' feature when the
satellite is down. When 'offline_mode' is on, Squid should
never try to contact an origin server. It would give cache
hits for everything.

With 2.3.STABLE3 you can toggle offline_mode via the
cache manager. For example:

        % client mgr:offline_toggle@SECRETPASSWORD
