My concern would be that by openly encouraging people to send in more reports of or inquiries about outages, we are going to see a lot more noise from unqualified folks wanting to "be cool". I personally don't want to hear about it every time someone wants to vendor bash ("@#$%^&ing GX is down again and their customer support sucks"), every time a T1 in Bumblescum Nowhere goes down, or otherwise completely useless posts ("did anyone see anything funky on level 3 on the east coast yesterday?").
Perhaps the best way to deal with that problem is to wait and see if it actually happens. In the past NANOG has carried a lot of these outage reports during a time when the net was less reliable than it is today. It didn't overwhelm the list back then. I would assume that because of the level of effort that operators put into having resilient networks, there would not be a huge amount of these outage reports because most real outages will remain invisible to customers. --Michael Dillon
