Nerds Like to Ping
A small note about latency, rituals, and why a round trip can feel strangely personal.
ping is one of those commands that turns an invisible system into a conversation.
$ ping -c 1 example.com64 bytes from …: icmp_seq=1 ttl=… time=… msYou send a packet out, wait, and receive a number that says how long the trip took. The number is not the whole story, obviously. Routes change. Queues form. Packets disappear.
Ask the network a plain question. Do not pretend the first answer is the whole explanation.
That is much of systems work: find the boundary, make an observation, and resist the urge to explain the result before you have enough evidence.
