Hi Vercel Support Team,

I'm experiencing an intermittent accessibility issue with custom domains connected to my Vercel projects.

Recently, I configured a custom domain, kwanat.com, for one of my projects. However, when accessing the website through the custom domain, it sometimes loads successfully and sometimes fails to load. Interestingly, the default project.vercel.app URL works consistently without any issues.

I've also tested the domain using several online tools that check website accessibility from different geographical locations. Two of these tests reported failures, as shown in the attached screenshot.

Here are the details of my current DNS configuration:

Domain: kwanat.com

Nameservers: ns1.vercel-dns.com and ns2.vercel-dns.com

DNS Provider: Vercel DNS

A Records: No A records configured manually.

What's particularly concerning is that this issue doesn't seem to be isolated to a single project. I've noticed similar intermittent accessibility problems across most of my projects using custom domains.

Could you please investigate whether there might be an issue with Vercel DNS propagation, nameserver resolution, or domain routing across different geographical regions?

I'd appreciate your help identifying the root cause, as this is affecting the reliability and accessibility of my websites.

I'm happy to provide any additional information or diagnostic results if needed.

Thank you!
