Thanks again Aaron

Here are some more findings from my location:

host avg ping traces through
www.eyedea.com.au 50ms Vocus
netvantage.com.au 55ms Vocus/alter
corporateinteractive.com.au 36ms optus
digitalpacific.com.au 38ms sisgroup/alter.net
anchor.com.au 50ms Vocus/alter.net
www.websitemanagers.com.au 38ms sisgroup/alter.net
tpg.com.au 37ms tpgi (?)
magikhosting.com.au 43ms vocus/alter.net
neubreed.com.au 36ms sisgroup/alter.net
crucial.com.au 52ms asianetcom
sphinx.techservers.com.au 38ms vocus/alter.net

I'm afraid I don't know enough about routing and peering to know what this data even means - all I know is that ping values were 35ms ish and now they're 50ms. The table seems to indicate *some* vocus sites are pinging slower than sisgroup, optus and tpg.

Are you able to check the sites above from where you are and see if you get the same differentiation?

I did some downloading tests this morning and those speeds seem to be fine - from the Telstra servers I get 310Kb/sec and from my server I get 286Kb/sec.

Please let me know if there's anything else I can do!

Hey John, is the increase ping for incoming our outgoing traffic from your VPS?

[jbngar]

I'm not sure I understand the question - do you mean am I pinging from my computer to my VPS, or am I pinging using Putty to the other sites?

I've just been pinging using a DOS prompt in windows, and tracerouting using PingPlotter.

Here's the same sites pinged from my VPS:

host avg ping traces through ping from putty
Eyedea - Creative Design, Web Development & Software - IDEAS THAT WORK 50ms Vocus 2.7ms
netvantage.com.au 55ms Vocus 8ms
corporateinteractive.com.au 36ms optus 1.6ms
digitalpacific.com.au 38ms sisgroup/alter.net 3.2ms
anchor.com.au 50ms Vocus 2.4ms
Website Managers - make the internet work for you! 38ms sisgroup/alter.net 2.9ms
tpg.com.au 37ms tpgi (?) 4.2ms
magikhosting.com.au 43ms vocus/alter.net 1.2ms
neubreed.com.au 36ms sisgroup/alter.net 1.6ms
crucial.com.au 52ms asianetcom 0.5ms

Doesn't seem to be any pattern there...

Also the slower pings seem to be not isolated to my VPS, crucial.com.au and 203.98.88.34 are running at 50ms instead of 35ms too.

I'd expect 50-60ms if I was pinging Melbourne or Brisbane - there's no chance things are being routed elsewhere or something? (Pardon my insane level of ignorance...) :-)

My question is are you pinging from your internet connection to the VPS, or from the VPS to other locations?

Can you please provide traceroutes for each of the above results?

[jbngar]

Aaron thanks so much for your time on this.

I'm pinging from Canberra, on a Telstra bigpond 8Mbps ADSL 1 connection (which has been throttled to around 3Mbps due to exchange congestion).

The traceroutes are attached.

Can you please login to your VPS, and provide a traceroute and ping results from the VPS to your internet connection? FYI, you can check what IP address your internet connection has by using ipchicken.com

[jbngar]

You're a dang genius Weller!

Looks like we're travelling to sunny brisbane and back!

The next question is [raises one eyebrow mysteriously] - WHY?

Why? Because I didn't reboot my modem. It must have been caching routes or something like that. I rebooted it, got a new IP and now I'm getting 32ms to my server which is quick as. Sorry for all the trouble Aaron - you can get back to your real work now! jbng :-)
