Except when there are /24-holder outages, at which point their traffic
gets hijacked by the /16 announcer. Would you want to trust some random
company to not take advantage of that situation in any way (collection of
passwords, sampling your web traffic, putting up a fake "your org" web
site, etc.)? As a holey /16 announcer, would you want all the junk
traffic that results from /24-holder outages? What if one of them was
running NS's for a popular DNSBL, and their outage basically caused a DDoS
attack against your network?
