That means that even when

for group memberships, and that will hang.

But why would it hang? The server wasn't just having trouble,
it was completely offline. Shouldn't something have noticed it
was utterly impossible to talk to the server and fallen back to
local lookups (certainly absolutely all of the "system" users
are locally defined - NIS is used only for "normal" users
and ssh login type stuff).

Anything that does a user or group lookup would have this delay in it.
You could possibly run nscd to cache user/group data or make sure your
sssd configs use shorter "force_timeout" and "offline_timeout" values
(both default to 60 seconds) to make it revert to local files sooner.
