check the archives whenever they are post, I'll bet 100 is closer

So much for fun. First I am a DIGEX customer (one of the ones mentioned
in the posting on the related threads). A couple of points:


    1) DIGEX brought a lot of resources when they were convinced there
was a problem.
       I discovered this over the weekend and it was fixed by Monday

    2) The notification sent out was at best ambiguous. My partner
       what they were saying and questioned them on it. They (DIGEX)
       our situation was covered (testing??).

    3) Clearly my class of service has been changed without any

Technical Issues
    1) As has been pointed out, the clear beneficiary of this changed is
DIGEX. As a 
       non-believer in hit counts, that part of the discussion has been
       But I think its clear this was done with the hope of increasing

    2) We are the guys with the obsolete proxy (netscape 1.12). Guess
what?? It does
       what we need, and DIGEX was fully aware we were using it before
turning on the
       cache. No testing here. So whoever made the point that they were
just letting
       problems fall out from operational glitches was pretty close.

    3) There are clearly experts posting to this thread that think the
gain will be
       marginal and/or there are other ways of accomplishing this goal
without the
       customer impact attendant with this solution.

I believe <ANTIFLAME> that most of the emails addressing these and
related issues dealt with the validity of doing this with or without
notification. </ANTIFLAME> I do not see how the issues above or the bulk
of these threads relate to using a new and creative solution.

To add one more amen to the chorus of many, I would be much happier
congratulating DIGEX on new and creative solutions if they would let
their customers know what changes are being made and perhaps even test
them a bit better.
