Perhaps I just have a corporate ASN, and my backup connection is the most I can afford to make sure at least email gets through when the primary is down. It's a slippery slope from "v.90 not good enough" to "less than 2xOCn not good enough" where n can be adjusted to suitably limit competition... -dorn

FW: [arin-announce] Change to Whois Query Behavior
by Mark Kosters 20 Sep '11

Apologies for the cross post from ARIN-Announce. Thought that many of you would be interested in hearing about the upcoming ARIN Whois change given the recent discussion on NANOG.
