EVERY IT PROFESSIONAL KNOWS THIS INCIDENT.
The application is down.
Developer:
“Application is working.”
Server:
“Server is fine.”
Network:
“Route is OK.”
DNS:
“DNS resolves.”
Security:
“Firewall has a rule.”
Everything looks good.
So why can't anyone connect?
The firewall rules are checked.
ALLOW — ANY → ANY → ANY
Looks good.
Then someone notices the rule above it.
DENY — ANY → ANY → ANY
PRIORITY: 1
Everyone suddenly goes quiet.
“Who put this here?”
“…Not me.”
Then someone checks the change history.
“It's been here since 2019.”
Case closed.
THE PRODUCT
Printed on the Comfort Colors® 1717 heavyweight garment-dyed tee for a relaxed, premium feel.
