Any quick script to see if a given domain ultimately resolves to them? My SaaS company has a lot of custom domains from whatever DNS servers pointed at us and I'd like to be able to tell people whether it's our fault or not.
- stevekemp 10y ago`whois $domain`. But it should be "obvious" if your users report "Server not found" vs. "Cannot connect" or "Page not found" style errors.
- mdavidn 10y ago`dig NS $domain` Query for the root domain, without any subdomains like www. That is, you need to check the "zone apex," the shortest name purchased from a registrar and potentially delegated to Dyn. Look for dynect.net in the list of authoritative name servers.
- patmcguire 10y agoYeah, I tried that. I don't see dnyect in a lot of domains that are failing, and it's clearly related somehow, they didn't all break at the same time by coincidence.
