Add this to your squid.conf:
 offline_mode on

Despite the name its not intended for use when offline. What it does is
make the cache extra 'greedy' and more likely to serve stale content
when the upstream connectivity is intermittent.

You can also look at the directive max_stale_hit and the max-stale=N
option on refresh_pattern.
