LOL. I just went though this the other day. my site was intermittently non-accessible. DNS was the last thing I thought it was until I ran a crawler on my site and spotted some 404 errors. Found that my non-www. url was pointed at the wrong IP and I forgot to update it when I transfered my domain to a new host.
Five stages of DNS outage:
1. Denial: It’s not DNS.
2. Anger: What the fuck is it!
3. Bargaining: Maybe it’s a firewall, or Cloudflare!
4. Depression: We’ve checked everything…
5. Acceptance: It’s DNS.
