Seattle (SEA) ping, RTT, jitter and packet loss, theoretical fiber floor, and route efficiency to 19 Hats Network (AS203314) backbone PoPs.

🇺🇸 Seattle (SEA)

Seattle is the US Pacific Northwest's primary interconnection hub and a key landing point for trans-Pacific submarine cables to Japan and East Asia.

Measurement round: 2026-08-15T04:03:13Z.

This page provides round-trip time (RTT) latency metrics between the Seattle (SEA) PoP and every other node on the Hats Network (AS203314) global backbone.

Average RTT from Seattle to every other PoP

Round average of 19 measured routes, sorted slowest first · whiskers mark ±1 standard deviation within each round

How to read this chart

Each bar is the average round-trip time of one 50-probe ICMP echo round from Seattle (SEA) to the destination PoP. The whisker at the end of each bar spans the average ± one standard deviation of that round — long whiskers mark jittery routes, short whiskers mark stable ones.

RTT vs. distance from Seattle

Average RTT against great-circle distance for the same 19 routes · shaded bands mark latency tiers · points are colored by continent

How to read this chart

Each point is one destination PoP: the horizontal axis is the measured average RTT, the vertical axis is the WGS-84 great-circle distance from Seattle. Points close to the bottom-left are routes that run near the physical fiber limit; points drifting upward-right follow longer paths. The shaded vertical bands mark the latency tiers (Ultra-Low <30 ms, Low 30–80 ms, Mid 80–150 ms, High >150 ms).

Fastest routes into Seattle

Measured RTT from 19 other PoPs into Seattle (SEA), sorted fastest first · each row spans min–max with a dot at the average

How to read this chart

Each row is one 50-probe ICMP echo round from another PoP into Seattle (SEA): the line spans the minimum to maximum round-trip time observed, and the dot marks the average. Short rows are stable routes; rows sitting far right are slow ones. RTT is not symmetric — the path back into Seattle can differ from the outbound path shown in the charts above.
