  Merit has a suite of useful tools available at www.merit.edu
  from the IPMA [Internet Performance and Metrics Analysis] group
  under collaboration w/ umich.  

  Included in this is a java client application that interacts
  with RA-esque server processes at IXPs.

  Additionally http://www.merit.edu/ipma/instability/origin/ 
  gives some daily information.

  Finally, http://zounds.merit.net/cgi-bin/do.pl?report_type=graph
  shows some useful aggregate information.

  Other information is abundant throughout the web page.
