[ale] OT Speedfactory Problems Anyone?

[Bob Toxen]

For problems like this, traceroute is your friend and can show where
the problem is in seconds!

Before tracerouting, I do:

     ping -c 1 yahoo.com

If it says "unknown host" or fails to output its first line with the
DNS resolution that normally looks like:

     PING yahoo.com (216.109.112.135) from 10.11.12.13 : 56(84) bytes...

then DNS is down.

Regardless of that, know the IP of a system on the Internet and then
do a traceroute to its numeric IP, e.g.,

     traceroute 216.109.112.135

You may want to give the "-n" flag to not do DNS resolution.
