Squid does so by default if it can.. or at least some times..

Detail: If squid refreshes a cached object and the refresh fails to
contact the origin server the cached object will be given.

However: If the client forces a cache bypass then the error will be
returned.

offline_node is related but not exacly this. It is more of a way to make
Squid be very aggressive about the freshness of what is has already in
it's cache.

Still the concerns with forced cache bypasses applies.
