Subject: The view from 16517

Hello;

I have set up two web pages describing the status of the Multicast 
enabled Internet as seen from AS 16517 (i.e., multicasttech.com). A
summary is available from

http://www.multicasttech.com/status/status.html

and the same information (but with more text, and intended for newcomers to
multicast) is available from

http://www.multicasttech.com/status/status.html

By popular request, this page includes a link to a list of autonomous
systems with multicast connectivity to AS 16517 :

http://www.multicasttech.com/status/mbgp.sum

This and all other information is updated at least 4 times daily.

Comments, etc. are welcomed. Please feel free to link to this site; if there are other similar
monitoring efforts out there, please let me know and I'll link to them.

BTW, this effort enabled us to almost immediately detect the loss of multicast connectivity
to Canarie on Friday, caused by a line break to StarTap. This problem was repaired late Saturday
night.

P.S. Our MBGP tables continually show evidence for AS leakage :
