Raise your hand if you ever inadvertently caused a 2+ hour outage (which was impossible to fix in a deterministic manner) due to DNS misconfiguration. #itwasdns
@geerlingguy My first thought upon hearing "it was dns" was you and your shirt.
Also my first thought the last hundred times something broke in the homelab and it turned out to be DNS.
Does it count when I recommended a DNS hosting provider who subsequently had a 2+ hour outage and we couldnโt even end the outage by moving to another provider because NS records from the TLD had a 24 hour TTL?
Ultimately we switched to managing our own DNS servers with replicas at 4 different hosting providers. That new setup has now run for over 10 years without a single outage.
