Presumably you have contact information for your own service providers. What if you find a problem, such as the Level3.net example, and you want to report it? whois tells all. Use the -H flag to turn off the reams of annoying useless legalese:

$ whois -H level3.net

Though it may be that the WHOIS information is out-of-date or false, it's still the first place to look.


Network Troubleshooting Tools by Joseph D. Sloan (O'Reilly, 2001), is a most worthy reference book for all aspects of network troubleshooting: hardware, software, and performance analysis.
