A root is not one static machine. Google can serve 1/3 of traffic for all routes, AWS could do the same.

I don't think folks realize how SMALL the root dns traffic is. Youtube / netflix / amazon prime video are just orders and orders of magnitude more demanding in terms of bandwidth - every second they are pumping MULTIPLE HD streams to millions of folks. They measure bandwidth terrabits per second. Even at 30 frames per second, we are talking incredible bandwidth.

DNS responses should be 1K or less (often .5K). About 40 netflix viewers at their top quality use the same bandwidth? Netflix has far more than 40 users.

You think the root operators should just delegate part of the traffic of all letters' VIPs to google and amazon? It's not crazy, but it would mean the entire root would have a shared-fate failure mode.

I don't understand. What's the failure mode you're thinking of?

Someone at Google pushes yet another invalid config of death, taking out their global network and, with this proposal, also taking down 1/3rd of all DNS root capacity.

You could easily 3x provision root dns (or more).

I'm just pointing out that for all the complaining about google efforts to block domain jacking (which was endemic before they started their efforts) scaling the root is doable, and if the existing maintainers are too incompetent to scale it then maybe others should be allowed to.

I mean, how do they handle denial of service attacks which are going to be orders of magnitude higher in volume?

The logic here is so warped.

Rather than the solution being to allow for domain hijacking by turning off the redirect detectore, how about verisign, which kicked this whole thing off recently AND way back with their "sitefinder" garbage get a clue and either propose another solution to domain jacking or scale the root a bit.

There already is precedence for this. Cloudflare provides a huge chunk of F-root servers.

Yeah, and it makes perfect sense for these big tech cos to run all or some of one root letter. But it violates the spirit of resilience to have one company participate in multiple letters.

Like Verisign does, ne? (-:
