Hi,

I've got a strange issue with 2degrees DNS that I can't seem to get a straight answer from anyone from. The issue is with DNS propagation to Google (and a few other) DNS servers.

When I dig the scenicgroup.co.nz domain for any DNS record for some servers (most noticably Google) it does not return any records. For most o thge others it does. e.g.

scenicgroup.co.nz@8.8.4.4 (Default): Copy results to clipboard
dig +noadditional +noquestion +nocomments +nocmd +nostats scenicgroup.co.nz. @8.8.4.4

The same query from CloudFlare or Open DNS returns records as expected

scenicgroup.co.nz@1.1.1.1 (CloudFlare):
dig +noadditional +noquestion +nocomments +nocmd +nostats scenicgroup.co.nz. @1.1.1.1
scenicgroup.co.nz. 300 IN A 119.47.120.70

scenicgroup.co.nz@208.67.222.222 (OpenDNS):
dig +noadditional +noquestion +nocomments +nocmd +nostats scenicgroup.co.nz. @208.67.222.222
scenicgroup.co.nz. 300 IN A 119.47.120.70

I have logged 2 x tickets with 2degrees who have done nothing and logged a ticket with Google DNS bug tracker and I got this suggestion:

There appears to be some sort of rate limiting/firewalling/access control or similar on your authoritative servers. From any IP controlled by Google that I've tried:

$ dig @ns3.snap.net.nz. scenicgroup.co.nz. A

; <<>> DiG 9.16.6-Debian <<>> @ns3.snap.net.nz. scenicgroup.co.nz. A
; (2 servers found)
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 1449
;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1
...

Your authoritative server refuses to answer, producing a SERVFAIL.

This to me looks like an issue with 2degrees DNS servers - can anyone shed any further light on this issue? This is affecting email and web browsing where google DNS servers are set.

Any help greatly appreicated.

Is 2degrees your domain NS host?

Any particular reason? Why not use Umbrellar - or even move DNS to Cloudflare?

It is on the list to change, but that does not fix my current problem quickly

Changing NS is probably quicker than waiting for the ISP to change their systems.

It could be rate limiting in an attempt to prevent DDoS in which case it will be a lengthy process to change.

I've just fixed this one up, should be good now - there was an error in one of the scenicgroup.co.nz resource records, causing SERVFAIL for the whole zone.
I'll respond to your support ticket with further details.

We are currently experiencing the same issue.

The website works fine on 2degreess mobile but not 2 degrees fiber. seems the DNS propagation has not taken effect?

Hi,

Got the sme problem now with a new domain: henterprises.co.nz - not propogating to Google DNS - most other servers are fine.

Logged 2 x job with @2degrees and the repose is to wait....any ideas?

I did see a post about using resolver servers in place of NS in another post https://www.geekzone.co.nz/forums.asp?forumid=85&topicid=272911

Should we be using new NS for DNS hosted at 2dregrees?

Hi,

There was an issue causing that not to propagate which I've just fixed.
Currently there's no resource records for that domain, you can add these via your Self Care Portal.
