https://newtrackon.com/ is reporting a 93% uptime for the live demo UDP tracker.

When you run netstat -su you see that apparently packets are not rejected.

I have also added a new metric for the announce request proceessing time and it's low (under 10 ms):

The processing time does not include the time sending the response to the client. https://newtrackon.com/ is reporting 222 ms for the response, which is under the 10 seconds they have set for the timeout.

Therefore I don't know why the uptime is only 93%.

I want to implement a simple script which is a loop to do the same https://newtrackon.com/ does. It will make an announce request every 5 minutes printing to console:

• The total number of timeout responses
• Average response time
• Last response time
• Maximum response time
• Miminum response time
