[AusNOG] Large Latency Spikes Normal on Australian VPS? Affecting VoIP

[Joshua D'Alton]

Perhaps paste a bunch of A and B end IPs, or at least subnets, but if you
see latency to purely the gateway of the local LAN, that is.. a problem
possibly, unless just COPP limiting.

Possibly though the provider you are with may not be top quality, or at
least there may be an underlying reason why such spikes happen. Although,
would be interested to know if it actually happens with VOIP, or just ICMP
packets?

Also, I wouldn't expect US/EU to show any more than 10ms let alone 100ms to
8.8.8.8 (actually better to do google.com, 8.8.8.8 is often not as close to
the hosting DC, you'll see <5ms to google, <20 to 8...), so again seems
strange to see any jumps to gateway/google.

I've experience with most if not all the VPS providers around (of note), if
you want to PM more detailed information be my guest!
