It's not DNS

There's no way it's DNS

It was DNS

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.

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.

whoa whoa whoa.. slow down! you dont just leap to "It's DNS"... you have to try to blame everything else first before you get to DNS. it's like foreplay!

when all of the interns have jumped around the corner before the blame hammer was wielded, you have to move to the next item on the list

It's always either DNS or MTU.

(Or, as I recently encountered, it can also be a McAfee corporate firewall trying to be helpful by showing a download progress bar in place of an HTTP SSE stream. I was sure that was being caused by MTU, but alas no.)

That ttl is a killer, eh?
