You did think of contacting them and asking? You know, e-mail, fax,
telephone, that sort of thing?

The first time I mentioned this company, I said that it is used to put
infected customers into a virtual router where all their internet
traffic is proxied via a server. which blocks unwanted addresses,
answers web requests not to designated servers from an internal
service - so going to google.com brings up the page explaining why
your account is quarantined.

The specifics of connecting it to your network, oddly enough, probably
will depend on how your network is built, which is why you might need
to contact them.

I thought this was a network operator's mailing list, not a
spoon-feeding session
