You need to start a thread to do that?  Is that what I've been doing
wrong all these years...

You staff account was expired on Saturday.  This action was taken because
your (former?) HOD chose not to sign for your account.  Basically,
costs were going through the roof, so the departments are now directly
responsible for the costs, instead of Prentice charging it directly to
general expenses.

It is really a case by case thing.  I believe that where speed is an
issue, it depends on the site's proximity to you.  For a 'close' site,
direct (no proxy at all) is faster than any proxy.  There is a point where
the network delays are equal to the cache delays.  So, you may want to
install a rule set into your proxy - something like, 'Parent to UQ proxy
only if its not *.au.'  Obviously, some experimentation is needed :-)

    Optimize for speed - buy out Telstra, proceed from there...
    Optimize for bandwidth - unplug the ... [carrier lost]

UQ's Proxies do have parents and they all have been upgraded over the
last month to improve performance.  Of course, bandwidth savings would
be a major point for any ISP.

Yours sincerely,

Mark Suter.
