The Score graph

A few times an hour the pool system checks the time from your server and compares it to its local time. Points are deducted if the server can't be reached or if the time offset is more than 100ms (as measured from the monitoring systems). More points are deducted the bigger the offset is.

The graph is only meant as a tool to visualize trends. For more exact details of what the monitoring system found you can click on the CSV link.

The Offset graph

The monitoring system works roughly like an SNTP (RFC 2030) client, so it is more susceptible to random network latencies between the server and the monitoring system than a regular ntpd server would be.

The monitoring system can be inaccurate as much as 10ms or more.
