WCCP allows transparent cache interception in a manner that can only ever
be fault-tolerant(*).

[(*) it does rely on the cache to 'stop' participating in WCCP 'hello'
messages. this is not normally hard to do in software design, but i
haven't actually looked at squid's source code to confirm it functions in
this manner -- but i'm sure it does.
its intrinsicly defined if the cache crashes.

yes. it will, however, take up to 25 seconds for traffic to be diverted.
