[Pdns-users] Problem with Linode NS Servers

[rob777]

Hi

I have posted this on /r/dns too - maybe someone here knows how to deal
with that

I have basically the exact same problem as this guy yesterday here:
https://www.reddit.com/r/dns/comments/1j9qj97/dns_recursion_to_domains_hosted_by_linodecom_not/

   -

   My Powerdns Recursor cant resolve stuff from the NS Servers
   ns1.linode.com , ns2.linode.com, ns3.linode.com
   -

   i can ping these linode dns server from my side
   -

   I've checked if my IPs of my recursor are blacklisted at linode.com -
   but i dont know if this list is for that exactly -> Client IP Reputation
   Lookup <https://www.akamai.com/us/en/clientrep-lookup/> but my ip is not
   listed
   -

   I have not any significant other errors besides these on my dns
   resolution with other domains
   -

   Prior to 11 of March it worked - i have changed nothing in my Powerdns
   Recursor recently
   -

   Debug Log of my recursor says Server Failure for alpinelinux.org (the
   same for others domain NS hosted at these linode NS Servers:

2025-03-13T12:38:17.346381+01:00 top-dnsslave-01 pdns-recursor[1048606]:
[816] QM alpinelinux.org: Step3 Final resolve: Server Failure/0

I cant open an Support Ticket at Linode because i'm not a customer
there...anyone knows how to deal with this properly?

Am i overlooking something on my side? IIt is no routing problem it looks
like i'm get "canceled" at port 53 of the linode.com Server. Could this be
some Akamai Filter.

I can post more debug log if needed but i dont see any solvable problem on
my side..
