We know the quality of your line. By quality we measure latency and packetloss of every DSL line every second. From this data we produce a graph that is updated every 100 seconds. The graph contains more than loss and latency, it includes:

Percentage of packetloss
Maximum, Minimum and average latency
Upload throughput
Download throughput
Line rate (ie download sync speed)
Whether the line is hitting download throughput limits (ie maxing out the download)

All the graphs are available to you and you can view them from the control pages.

Examples

Streaming

Streaming to Twitch at around 5Mb/s (Dark red line is the upload traffic)

This line is looking good, no packet loss, and a good constant upload of about 5Mb/s which is video streaming to Twitch.

Packet loss

A line with no traffic, but has constant 1-2% packetloss (red dots at the top)

Loss like this, however small, will affect the performance of the line incredibly as packets will need to be re-transmitted making things very slow. This is a line with a fault that will need to be diagnosed and fixed.

A line heavy packetloss - probably pretty much unusable

Huge amounts of packetloss, even downloading a simple email will be hard work here! This is a line with a fault that will need to be diagnosed and fixed.
