There are some business reasons to de-aggregate. Look at some outages caused by 'routing problems' (someone leaked my /24's to their peers, peers, peer and my traffic got blackholed, because the public net only knows me as a /20)
I am surprised you bring such an argument up. While we can surely agree on this happening on the net, I have yet to hear from someone saying this is happening more than once a month or so. Maybe Todd from Renesys has other examples besides the Yahoo incident.^
if it happens once to you and lasts long enough... I'm not condoning it, nor saying it's even a valid reason to do it, just pointing out that it does happen :(
There are multiple reasons for deaggregation aside from 'dumb operator', some are even 'valid' if you look at them from the protection standpoint.
I won't argue that, but how many ISPs are using this line of argument? I have not heard anyone yet telling me this, not in years.
a few have... recently in fact.
