[URGENT] My domain is still inaccessible after 2 days. I'm pretty sure I configured Route 53 correctly. I need help.

0

Ok so I got the confirmation of our domain name transfer from OVH on Sunday. While waiting for the transfer (which took 10 days), I copied all the DNS records to Route 53. The MX records were already configured for our GSuite, so I was expecting the our email box would never stop working. I removed the automated OVH stuff and replaced it with Alias records to our Beanstalk loadbalancers and Vercel deployments. The Test Record feature shows that the records are working correctly, even with different resolver IPs. BUT after 2 days, our website is still inaccessible, and our mailbox isn't receiving any emails. nslookup returns SERVFAIL errors, no matter with public resolver I try (8.8.8.8, 1.1.1.1, etc). I'm out of ideas, I don't know what to do, and every hour that passes without being able to receive emails is business that we're losing.

It’s most likely your Glue records are incorrect.

When you transferred your domain, you may or may not have updated your Glue Name server records.

Look in your route53 zone file for your NS records. There will be 4 name servers.

Then head over to this link and update your name servers on your domain https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/domain-name-servers-glue-records.html

    What are your name servers set too in your domain? Not the zone but the name servers for your domain?

    Use my link above to make sure the name servers set match your screen shot.

    You update name server records in route53 per link not at ovh as you transferred the domain.

    Oh ok I found it. Because the NS records were set automatically to AWS DNS I thought you would also make the change to the domain's DNS as well. But no. Plus I didn't know where to find the DNS names for my domain so I had to look around a bit, and then when I found them I realized they were still set to OVH's. It's fixed now. Thank you

Hi,

You should go through this guidance: https://repost.aws/knowledge-center/route53-dns-servfail-response to validate that your problem doesn't come from one of the listed causes for DNS SERVFAIL errors

Stating that you're pretty sure of the Route53 settings and that it is a transfer from OVH, you may want to start with the first possible cause in the list "A third-party name server (NS) is blocking the AWS public resolver's IP address"

In particular, you should check via nslookup directly (nslookup [domain-name] [name-server]) on OVH servers if they still directly publish infos about your domain

Best,

Didier

    You mean I need to go back to OVH to update the DNS names to Route 53's ? But why would I need to do that? The domain is transferred, right? Why would OVH still publish infos about my domain? I'll try of course but I'm a bit confused here.
