1.1.1.1 and 1.1.1.2 suddenly resolving outside the US

Starting about a week or two ago, we started seeing that 1.1.1.1 and 1.1.1.2 are resolving randomly to outside the US for several domains. The best one to test with is finance.yahoo.com. For example, my most recent query for finance.yahoo.com returned the following:

106.10.236.40
119.161.10.12
119.161.10.11
106.10.236.37

My IP is in the US, and google resolves the same query consistently to the following:

69.147.88.7
69.147.88.8

Why is Cloudflare suddenly throwing me all over the world?

¡Hola @TheHulk!

Happy :taco: Tuesday!

Albeit I do see slightly different results over at

nothing as extreme as you do.

Could you please provide us with the plain text output of the following commands so we can get a clearer picture of the issue you’re facing?

mtr --tcp 1.1.1.1
mtr --tcp 1.1.1.2
dig +short @1.1.1.1 id.server CH TXT
dig +short +tcp @1.1.1.1 id.server CH TXT
dig +short @1.1.1.2 id.server CH TXT
dig +short +tcp @1.1.1.2 id.server CH TXT

¡Gracias!

Sorry for the late reply. I’m still seeing this issue from our west coast data centers. Unfortunately I don’t have a linux box to be able to run those commands. I can provide some Windows ones though.
