That implies a routing issue, outside your box.  (I used to do senior 
support for an ISP; I know these things.)

The machine is probably behind a firewall that doesn't accept pings to 
prevent DDOS attacks.  Try this:

traceroute www.globus.org

If you get lots of timeouts, you may need to use ICMP packets, but for 
some weird reason, that requires root.  (I do it often enough that I've 
set suid on /bin/traceroute but I'm not suggesting anybody else do 
that.)  If the above gets complaints, use this instead:

su -c 'traceroute -I www.globus.org'

Will show you how close you're getting and if there's any routing 
problems.  I used su -c because I *don't* use sudo on my home machine 
and don't expect anybody else to either.  YMMV, and if you're more happy 
with sudo, substitute as needed; it's your machine, not mine.

Once you've documented where the issue is, call your ISP and let them 
deal with it because that's what you're paying them for.
