I was cleaning up DNS and found a record called:
OLD-PAYROLL-PROD
It pointed to a server named:
DO-NOT-DELETE
No owner.
No documentation.
No tickets mentioning it since 2019.
I asked three senior engineers what it did.
Nobody knew.
So naturally I deleted it.
Four minutes later every hourly employee disappeared from the timeclock system.
I restored the record.
Everyone came back.
We still don't know what the server does.
We don't know where it physically lives.
We don't know who pays for it.
We don't know why DNS controls payroll.
We only know that if it disappears, 600 people stop getting paid.
I renamed the record:
DO-NOT-DELETE-SERIOUSLY
Audit asked me to document the dependency.
I listed the system owner as:
“Ancient forces beyond our understanding.”
