How good is your IPv6 connectivity?

What that ABORTED shows is that Squid successfully connected to the
server, but 0 bytes had been received back before the client gave up.
This process took around 30-60 seconds to happen, so the client is not
particularly impatient.

It is not uncommon to see these types of things on networks where people
have IPv6 operating over a broken tunnel, or have disabled ICMP (ICMP is
not optional in IPv6).

This tool may help determine the problem:
