This page is old. It is republished every hour; when an update is missing, the monitor usually could not reach the internet to publish, which itself points to a line fault. The next successful update will include that period.

Latency (ms, per-minute average; shaded spans are logged events)

Packet loss (%, worst minute)

Where the loss sits

For every second in the window where at least one external host dropped a ping, was the home router or the provider's first hop also silent at that same instant? Seconds during the monitor's own throughput tests are excluded.

Seconds with any external loss	All external hosts lost	Home router also lost	ISP hop also lost	Lost beyond the first hop
52 of 85,245	1	4 (8%)	52 (100%)	0 (0%)

Reading it: a high "home router" share means the problem is inside the property. A high "first hop" share means the provider's gateway itself is dropping traffic. A high "beyond" share means packets get past the first hop and are lost deeper in the provider's network or upstream.

Events (provider-attributable, newest first)

1 of the degraded rows above are single-resolver blips (one DNS host unreachable while the others answered) rather than line faults.

How this is measured

A monitor on a wired machine behind the home router in Sandhurst pings the router, the provider's path hops and three independent external hosts (Cloudflare, Google DNS, OpenDNS) once a second, checks DNS every 15 s and HTTPS every 30 s, and runs a throughput test every 240 minutes. A one-second state machine classifies each moment: router unreachable = home problem; router fine but every external host unreachable = provider outage; sustained loss ≥ 10% or latency ≥ 150 ms = degraded. The minutes in which the monitor runs its own throughput test are left out of every figure and chart.
