Can't get TXT result for 71.129.160.5.3000000000012.sb-adfe2ko9.senderbase.org against 1.1.1.1 / 1.0.0.1

Hello,

I am suspecting a cache issue somewhere at the Cloudflare side but I can’t figure out where is the issue exactly.

As you can check from your side using “nslookup -q=txt 71.129.160.5.3000000000012.sb-adfe2ko9.senderbase.org 208.67.222.222” it always works and returns a result.
But the same command line against 1.1.1.1 or 1.0.0.1 always fails with a timeout.

Using “dig TXT +noadditional +noquestion +nocomments +nocmd +nostats +trace 163.93.96.84.3000000000012.sb-adfe2ko9.senderbase.org. @1.1.1.1”, you’ll see that everything seems fine.

Could you please help me to understand what is the root cause of this behavior ?

Do not hesitate if you have any suggestions / ideas.

Please note that this issue started to occur last Friday and that I don’t want just to solve the issue but at first to understand the root cause.

Thank you,
