Yes. "000" means no response came back after passing on the request to
"x.x.x.x".

It is not an important problem affecting Squids operational stability.

You can use telnet from the Squid server:

  * Open a telnet link to "x.x.x.x" and the cache_peer port Squid was
configured for it.

  * Send the text "CONNECT remoteaccess.epsnetwork.com:443 HTTP/1.0"
then press enter twice.

  * Expect "HTTP/1.1 200 Okay" or similar to come back.

If that fails it is the other server.
