When it fails to connect to it. A peer is declared dead when 10 TCP
connections have failed. Dead TCP peers are also probed using TCP to
detect when they come alive again.

Squid versions up to 2.1 temporarily returns an error until a dead
TCP-only peer is found to be truly dead. Squid 2.2 will handle this
transparently.
