Generally problems are what start people thinking about solutions.. ;-)

Definitely. I see the critical need as not publishing generic uptime
statistics, but network health information. That's not only what
informs users as to why they can reach X web site, but also for consumers
to choose their providers; among other benefits.

This sort of testing would also lead to false conclusions, IMHO. Lately
the backhoe appears to be taking the lead. :-)

I can't suggest a third-party at this point, but as my cohort Alan Hannan
pointed out, following the discussion last month we have begun working on
proposal material. Unfortunately it really hasn't received the
attention it should on my priority list.
The key in obtaining the data is for the individual providers themselves
to contribute it. There should be no reason why an organization needs to
maintain a staff simply to monitor another's backbone and publish the

Unfortunately the telephone is still one of the best methods for reliable
communication, IMHO. One of the bits that amazed me back in the day
('bout 2yrs ago) at BARRNet (not a pot shot) -- is that when the network
had an outage, an Email was sent to an outage list. Well, if your network
link is down -- how can you get the Email? One particular customer
mentioned to me that when I called him during an outage, it was the first
time he had been contacted during an outage. Normally he had to wait and
digest the Email after his service was restored.

Nice idea, but much more difficult to implement. You're talking about
convincing quite a few people to implement it. Part of a NOC's mission
is to deal with incoming calls, or in certain cases Customer Service

Definitely; the model we're currently toying with would be open
enough to be accessed both by provider's NOC staff as well as individual
consumers on the Internet. The access method would be Web based and
offer an Email interface for those desiring automated status reporting or
simply a different view.
Providers would be responsible for submitting incident reports and
keeping them current (e.g. ticket updates); and a user could browse as

Probably lots more effort than has been put in thus far. :) I would
imagine a short presentation could be prepared explaining the model and
who has "agreed" to support it by NANOG. However, a worthwhile
presentation should include stats on who has used the service and if it's
