In all seriousness, one has the basics like traceroute, ping,
route servers, looking glasses, et cetera.  However, those tools
only give a view from a certain point or along a path... they
provide a limited cross-section of a complex N-dimensional beast.

Bill was right:  Sean Donelan's posts are very handy.  And I was
only halfway being a smart-aleck... if one deduces that there
just _has_ to be something anomalous, posting to NANOG is an
amusingly low-tech "distributed layer-9" diagnostic.

Note that I'm assuming you refer to internetwork diagnostics.  If
you seek intranetwork diagnostics, one has SNMP and other tools.
