outage

cf brian nisbet's talk this (cest) afternoon: a fair number of researchers are obsessed with outage detection. they have a problem; outages where one can know the 'ground truth' (operator confirmation of what actually happened down to the links and times) is very hard to get. so, it would be helpful if some core networks would either report the details of an outage every week or so, or create a nice variety of planned outages and descrive the details. randy
