Ask HN: Is Route53 working for you?
I am getting very strange issues from it since a few hours. Another IoT attack to DNS?

Response from AWS Support:
We have investigated this issue and are seeing incorrect responses from two of the .io nameservers: ns-a4.io and ns-a2.io.
These nameservers are returning NXDOMAIN intermittently for domains that do exist. As a result, once a resolver receives the erroneous response, it will cache the non-existence for the negative TTL, which for .io is set to 3600 seconds (1 hour).

Those broken .io nameservers seem to be taken down now. So next cache flush should fix the issue.
nice that they replied to you. Still waiting to see a reply from them...
Enterprise Support customer here :)
It looks like the bad .io servers aren't responding to requests anymore, at least from my location. I have flushed a bunch of my own records on public Google DNS: https://developers.google.com/speed/public-dns/cache

I've had issues with DNS resolution on apps hosted on Engine Yard and Linode in the past hour. I'm afraid there might be something going on indeed.
Lots of folks reporting issues with Route53 atm, especially with .io domains.
This is actually one of the few times Twitter is super-helpful!

How do you get updates on services there? Do you search for particular keywords? Follow particular accounts? Interested for a friend :)
Our .IO is not working but our .NET is working
And no AWS incident page
Yes, just had a small hiccup -- seems to be working now...
needless to say https://status.aws.amazon.com/ is all green :(
manually editing our /etc/hosts files nice! poor man DNS solution
