Re: Reference

Anyone know of a good place to check on the historical data about how many times a route has flapped in the last X amount of time?

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. -alan
