Massive DNS Trouble, CloudFlare's 1.1.1.1 down
Widespread DNS trouble in the last few hours, including an outage of
CloudFlare's 1.1.1.1.

Maybe related to CVE-2020-1350? I doubt it.

Early report, more info coming.

Thank you for the response Justin! But I don't think it was just you
guys. I started seeing corrupt/malformed DNS responses around 16:43 EDT
from open resolvers like thumper.fastlink.net (192.34.59.231) among others,
and large portions of Microsoft's Azure TrafficManager.net DNS platform are
still down in the IAD/Ashburn region.

I doubt this was all related to CVE-2020-1350, but maybe?

Thanks for all that you and the team do.
