First hint: you are still using a *beta* release of Squid-3.1. That
series has been in stable releases for over 2 years.
NP: I advise using no release older than 3.1.15. There are major
security vulnerabilities in all older releases.
Second hint: that 503 status generated by Squid means no destination
could be contacted. ie the TCP connection setup failed. "Error 111
(net::ERR_TUNNEL_CONNECTION_FAILED): Unknown error." is Chrome
"user-friendly" display the 503 failure status.
Guesses:
DNS resolution of AAAA and A records failed (no destination able to be
found).
TCP connection to some found IPv6 address(es) failed
TCP connection to some found IPv4 address(es) failed
NP: the problem is very likely to be your IPv6 connectivity or some IPv6
issue in that 3.1 beta release. Google services are mostly IPv6-enabled
and using HTTPS (via CONNECT) since earlier this month. Squid-3.1 will
try very hard to connect using IPv6 whenever possible.
