Hi, after about 24 hours I have monitoring data that shows packet loss of about 1-2 Packets per Minute (which means for the 0.5 s packet interval of the monitoring less than 1 % packet loss). The latency is very unstable and moves between 340 ms and 440 ms. My monitoring system is located in Germany and connected via Level3 and Deutsche Telekom (DTAG).
Nontheless is the offer for donating a monitoring node inside china by [email protected] with the monitored latencies the better option. By tunneling traffic between US and Europe you will get additional ~100 ms on top.
