This probably doesn't help much in nailing it down.... An outage is major if the general public and the press would perceive it as an Internet outage rather than a single provider outage. A multi-provider outage counts. So does a single provider outage that affects a large enough geographic area that the public would perceive it as multiple outages, i.e. the Internet is down in Boston and New York and all over the place. Even a single provider outage at a backbone that causes outages at several ISP's in a single city would be an "Internet" outage, especially if the backbone were to be one of the dialup modem suppliers to nationals like Earthlink, AOL, et al. I guess the point I am trying to make is to start from public perceptions since we are talking about mainly the reporting of an analysis for publicly known outages. If a SONET ring fails over then there is no publicly known outage. But when it starts to affect multiple points then the public takes note and it is a significant outage that we need to learn from. Could be multiple geographical points, multiple circuits, or multiple providers. -- Michael Dillon - E-mail: michael@memra.com Check the website for my Internet World articles - http://www.memra.com
