I thought DNS (particularly public) was basically immune to DDoS? If one DNS server is down, use the cached result or another server. DNS is some of the most distributable, cachable data I can imagine.

Seriously, please someone explain this. I thought DNS info is propagated among DNS servers, and it is cached on all of them... How can an attack to a single DNS company cause this outage??

Explained above for ya

All this talk about redundancy, real-time apps, scalable architecture and and a "simple" DDOS against DNS architecture brings half of the internet down. Honestly did nobody think about having a spare dns at some other company? or even backup dns server exactly for a situation like that?

Maybe it is time to widely adopt namecoin ?

Yes!! For sure, after such an attack it will force the internet into rethinking their DNS strategies. Why commit to having a single point of weakness?

You can find any other IPs you need on sites like http://www.hcidata.info/host2ip.cgi

Just remember to rollback your hosts file after the outage finishes.

Earlier quoted context omitted.

From where I'm looking at the internet (central Europe), I don't notice anything. Maybe your internet on the other side of the Atlantic is broken, ours seems to be working fine. ;-) Edit: Looks like the eastern part of the USA is affected: https://cloudharmony.com/status-for-dyn

I'm in Las Vegas and I haven't had access to several sites all day. I don't think this is limited to eastern U.S.

Same Im in Illinios and I can't play destiny which is made by bungie which is down for some fucking reason

This is not a dyn error, this is all the companies failed to prevent this to happen, is an old practice having different NS Servers for your domain, but it can prevent this to happen.

It appears that people (domain name administrators) are switching away from Dyn as their DNS provider, as per https://status.heroku.com/incidents/965 (issued 19:21 UTC). Does this mean that other DNS providers (Amazon Route 53, CDNetworks, CloudFlare, DNSimple, easyDNS, Google DNS, Verisign, OpenDNS) could potentially become targets?

confirmed three (3) coordinated attacks on Dyn's infrastructure today: 11:10 UTC, 13:52 GTM, and the third time is unknown -- Dyn has not specified the time of the 3rd attack today on their dynstatus.com page (likely because the whole thing can be considered ongoing). Can anyone speak to when the 3rd attack began today?
