   I have had recent problems with my ADSL, now I hope cured, and I was only
able to ping or traceroute as far as some local BT machines. It seems that
many ISPs are not currently providing some standard services such as ping or
echo (used by traceroute) that have been used by recent M$ viruses, so I am
not able to confirm what the problem was, either mechanical, equipment, or
software failures, or overload due to virus attacks, although in my case it
appeared to be outside the control of my ISP.
