Ask HN: Is anyone else seeing slow DNS?

I'm seeing DNS requests taking a very long time to resolve, both at work and at home. Different transport, different computers, even different OSes. I've been seeing this for a couple of weeks.

Is anyone else running into this? Anyone know what's going on?

If you checkout this script [1] what numbers do you get?

Hmm. Nothing very horrible. 20 ms to 200 ms.

Next step would be to add whatever DNS resolvers you use into that script then compare.

Also different DNS servers?

https://www.dnsperf.com/ does DNS services monitoring.

Personally I think something might have happened over at root server level as I had issues while working with dig and whois tools.

Yes. my home network is super slow and usually I blame Comcast but this is different.
