I should clarify I wasn’t a upper level sys admin managing those servers, I just used them or maintained accounts being a rank and file technician
While I get the fundamental concept of DNS as a phonebook for your IPs. I am not sure why it is joked around if something goes haywire or someone breaks something.
Is it because if you get no DNS, people can’t log in through their AD accounts, browse the Internet?
Afaik DNS is a bit of a rabbit hole topic, maybe that’s why people joke about it due to DNS being this “No one really knows how this magic name matching box works”?
Please correct me, I’d genuinely like to know why this is prevalent from you guys.
When it is the cause of a problem it’s not always obvious at first so you spend hours troubleshooting the broken app until you look at DNS and a simple DNS issue
Often because we know how badly things can go wrong with so many components we start at the end of the app instead of the beginning.
Similar to how tech support always asks of you rebooted. We often don’t confirm basic connectivity issues.
I’ve had a problem like this yesterday. I couldn’t access my paperless instance. I eventually figured out I could access it with an IP + port combination and the DNS lookup failed.
