This is just a horribly painful example of why we/they should all follow the route of NetFlix ( http://techblog.netflix.com/2013/05/denominating-multi-region-sites.html ) and use multiple DNS providers. Denominator ( https://github.com/Netflix/denominator ) the tool NetFlix uses for this and open-sourced, currently supports managing (mirrored) DNS records across AWS Route53, RackSpace CloudDNS, DynECT and UltraDNS.

It is a shame in that PagerDuty is affected.

However, Dyn is far, far better positioned to withstand attacks than a company like PagerDuty could possibly be on their own. So I think PagerDuty did the right thing in using Dyn.

Remember, Twitter, Pingdom, github, and lots of other people use Dyn. And this is the first major outage I have heard of their service.

Let’s all be clear that Dyn has to be in the top 10 DNS infrastructures on the planet. Possibly the largest that sells DNS as a service. This is a serious attack, and the entire community should help track this miscreant down, then crush them like a bug.

It's a shame services like PagerDuty use Dyn. Now they're down too...

Previously it was not affecting upper midwest for me, traces went to
Chicago.

Now traces to twitter DNS servers in Chicago are failing.

The attacks appear to be continuing again. We are experiencing issues in
Europe/Asia.
