One of the biggest mistakes I see during network troubleshooting is this:
  
"Ping is successful, so the network must be fine."
  
A successful ping only proves one thing:
  
An ICMP Echo Reply was received.
  
It does not confirm that the application, firewall policy, routing, DNS, or user experience is working as expected.
  
Over the years, I've learned that relying solely on ping results can lead engineers in the wrong direction.
