Indeed. We currently monitor each part of our operation from a monitoring station on our network. Under certain conditions, this can give us both false positives and false negatives:

Umm... Keynote? (http://www.keynote.com)

I find it truly amazing that people don't already diversely monitor. Hell, have cronned pings running off your friend's cable modem if that's all you can afford, but for christ's sake, a single box colo'd in someone else's cage, or a shell at shells.com or nether.net really isn't that expensive.

Might be interesting to define a set of basic monitoring functions that independent ISPs can run on each other and share results. Early warnings could go to a special email.

Concillience <http://www.concillience.com> already provides this as a third party service. They have located agents on a variety of networks world wide, and are able to provide both real time alerts, as well as longer term trending information. Their data collection service has the ability to track things like "Network X has low throughput to Network Y.", and similar kinds of issues. Keynote goes part way to a solution to this problem, but, IMHO, doesn't go far enough. -- Justin W. Newton Senior Director, Networking and Telecommunications NetZero, Inc.
