I am not able to use 1.1.1.1 for DNS resolution but the 1.0.0.1 address is reachable.

Is this something that I can fix on my end and if so any pointers to how?


#2

Interesting, it seems it stops right at the hop before Cloudflare. Which datacentre are you hitting?


#3

Can you advise how I can determine what datacentre I am using?


#4

Which operating system are you using?


#5

I have tried on Linux Mint 18.3 KDE and unRAID (Slackware) with the same results.


#6

In that case, whats the output of

dig +short CHAOS TXT id.server @1.0.0.1

#7
|-[14:15:24]-> dig +short CHAOS TXT id.server @1.0.0.1
"ATL"

#8

You seem to go via Atlanta. Maybe a glitch over there.

#9

I am South of Nashville, TN so Atlanta certainly would be plausible.

Any ideas on how to resolve this issue? Still no joy as of this morning.

@cloonan, @cscharff, any known issues in the ATL DC?
