Summary
- Bandwidth measures capacity; latency measures how long a useful exchange actually takes.
- Operators need regional, percentile and transaction-level evidence rather than one average ping.
Internet latency is the delay between an action and its result. Distance sets a floor, but congestion, poor peering, retransmission, DNS, encryption handshakes and slow application code add their own waits. Averages can conceal the users who experience the worst paths. Teams should measure complete transactions from representative locations, separate network delay from server time and keep high-percentile results. The next useful evidence is a route or application change that lowers those percentiles without shifting failure elsewhere. That links investment to experience instead of to a laboratory speed figure.
