According to Fortune, Hacker News "reported" on the incident. Are we journalists now? "Popular tech site Hacker News reported many other sites were affected including Etsy, Spotify, Github, Soundcloud, and Heroku." -- http://fortune.com/2016/10/21/internet-outages/
Out of curiosity, why do caching DNS resolvers, such as the DNS resolver I run on my home network, not provide an option to retain last-known-good resolutions beyond the authority-provided time to live? In such a configuration, after the TTL expiration, the resolver would attempt to refresh from the authority/upstream provider, but if that attempt fails, the response would be a more graceful failure of returning a la…
OpenDNS does this: https://support.opendns.com/hc/en-us/articles/227987767-Dyna... It's called SmartCache.

Historically, doing this has been a source of a truly awe-inspiring amount of pain.
Earlier quoted context omitted.
Yes, but: 1) Memory and disk are cheap. My caching DNS resolver can handle some stale records. 2) I suggested above that this behavior would continue until an administrator-specified and potentially quite generous maximum TTL expires. That is, I could configure my caching DNS resolver to fully purge expired records after, for example, 2 weeks.
> 1) Memory and disk are cheap. My caching DNS resolver can handle some stale records. The problem is not that it would require storage but that stale records can be outright wrong. That timeout would require configuration and DNS does not provide that. So sure, a new timeout could be introduced but that currently does not exist in DNS.

> The usual thinking goes something like; well, the US created the internet so why would they want to take it down? To pin it on someone else? "17 Intelligence agencies told me Russia hacked our DNC thing" (Clinton). So maybe it is now "Oh look they took down the whole internet as well".
>To pin it on someone else? That's... kind of conspiratorial thinking? Would you cut off your own hand so you could blame it on someone else?

Better yet, have one day a year that is "Red Team Day" where people hunt for vulnerabilities so that assessments can be done, and companies can later fix any issues noted. Like how earlier this week there was a statewide earthquake drill in California, local emergency sirens were sounded, schoolkids practiced hiding under desks, etc. The Internet needs periodic tests like that too.
Not sure if related but circleci.com is down for us do to a "DNS issue" !
I'm a GitHub employee and want to let everyone know we're aware of the problems this incident is causing and are actively working to mitigate the impact. "A global event is affecting an upstream DNS provider. GitHub services may be intermittently available at this time." is the content from our latest status update on Twitter ( https://twitter.com/githubstatus/status/789452827269664769 ).
