About
Network quality between to points can be tested by using iperf tool.
On client site:
iperf -c SERVER_IP -u -b 10m
On server side:
iperf -s -u -i 1
"Datagrams" column should be checked in server side. High percents means network problems.

Example
For testing you can use one of our servers. In order to test your connection run this command:
iperf -c 91.121.143.102 -u -b 10m
You will get a similar result:
[mindaugasm@quad ~]$ iperf -c 91.121.143.102 -u -b 10m

69% is a very bad result here, the closer this result is to 0 - the better the situation with our network is.
