Definition

In depth

Traceroute is how you localise where a latency jump or packet loss appears — inside your house, on your ISP, at a transit provider, or on the game's own edge.

Reading traceroute output requires care: ICMP is deprioritised on many hops, and mid-path spikes are often cosmetic. What matters is loss and RTT growth on the final hops.
