The noise of origin changes is fairly heavy, somewhere in the low hundreds of alerts per day given a 3 day history window. Supposing a falsely originated route was delayed, what is the chance of identifying and fixing it before the end of the delay period? Do operators commonly catch misconfigurations on their own or do they usually find out about it from other operators due to service disruption?
Are the origin changes for a small set of the prefixes that tend to repeat (eg: connexion as planes move), or is it a different set of prefixes day-to-day or week-to-week? I suspect there are the obvious prefixes that don't change (eg: 12/8, 18/8, 35/8, 38/8) but subparts of that may change, but for most people with allocations in the range of 12-17 bits, I suspect they won't change frequently. - jared -- Jared Mauch | pgp key available via finger from jared@puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine.
