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 126.96.36.199.3000000000012.sb-adfe2ko9.senderbase.org 188.8.131.52” it always works and returns a result.
But the same command line against 184.108.40.206 or 220.127.116.11 always fails with a timeout.
Using “dig TXT +noadditional +noquestion +nocomments +nocmd +nostats +trace 18.104.22.168.3000000000012.sb-adfe2ko9.senderbase.org. @22.214.171.124”, 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.
