Its not clear to me which parts of this you control, and which parts
you do not. I will assume that all requests go you your Squid cache
and that your upstream ISP is using HTTP interception.

You can define a parent cache and forward only certain requests to it.
for example, you can sign up to use one of the IRCache proxies
(www.ircache.net) and use a Squid configuration such as this:

  acl BlockedByISP dstdomain www.example.com
  acl BlockedByISP dstdomain www.example.net
  cache_peer parent ny.us.ircache.net 3128 3130
  cache_peer_access ny.us.ircache.net allow BlockedByISP
  never_direct allow BlockedByISP
