Why does my VPS have high packet loss?

Does it?

Are you testing for packet loss by attempting ping floods, such as this:

root@laptop3:~# ping -f vpsserver.tocici.com
PING vpsserver.tocici.com (199.223.127.179) 56(84) bytes of data.
..........................................................................................................................................^C
--- vpsserver.tocici.com ping statistics ---
163 packets transmitted, 25 received, 84% packet loss, time 3390ms rtt min/avg/max/mdev = 222.970/256.924/384.846/54.685 ms, pipe 25, ipg/ewma 20.925/249.431 ms

If so, then of-course you'll see packets loss; ping floods are considered a denial of service attack. Our extremely sophisticated border routers will auto-detect your activity, and then block it. Frequent attempts to flood external networks with excessive ICMP traffic will result in a ToS shutdown of your VPS. We don't care who's network you're attempting to flood with ICMP traffic, there's no legimiate reason to waste resources like that, so, stop it.

Appropriate tests

Determining source of packet loss or high latency

Are you trying to determine the actual source of where packet loss or high latency is being introduced? If so, then we highly recommend using the tool MTR. MTR combines the functionality of 'traceroute' and 'ping' into a single network diagnostic tool.

Long-term trending/visualization of packet loss, latency, and jitter

Are you attempting to measure and visualize networking behaviors over a long period of time? If so, then we highly recommend Smokeping. See their website for more details.
