      I’m working to improve our network configuration with a change coming to our web site very soon, if you’e interested in helping out please run the following commands from your command line (start > run > cmd) and paste the results below. Ideally the more samples I have the better, particularly from a wide variety of geographical locations:

      ping 66.228.118.51
      ping 67.228.118.21
      ping 208.43.118.51

      Cheers!

                      I think you’re using XP so its Start Menu > Run then type in “cmd” in the box

                      type the ping command with IP address into the black “old style computer screen” box what appears.

                                Could you traceroute the ip and post the result?

                                    It’s not network performance test but a ISP performance test.

                                      normally it would be but Dr B is trying to balance the load across 3 servers which are presumably all in the same data-centre and on the same network – except for some reason I cannot access to 67.228.118.51.

                                      Can anyone else get to it?

                                      I could try with a mobile phone and my netbook but the mobile I would use has run out of battery charge anyway and TBH I have drunk too much beer now to be bothered to fetch all this equipment, particularly if the routing fault is in the USA anyway!

                                        Here’s some MTR’s from a box in maidenhead. If you want any advise give me a shout. You shouldn’t need to load balance anything though, given the amount of traffic you get should be handled no problem with one box… curious why it’s balanced over 3 servers. Anyway here’s the output, given it’s in the US though you’ll get not-so-useful results from the UK. All these go through hurricane electric who handle my transit from London to NYC so the traffic stays on the same network across the water. I’d probably recommend moving to the UK if you want any noticeable improvements from a network POV, especially for latency and jitter.

                                        General Lighting FYI: 67.228.118.51 blocks ICMP echo requests hence why you can’t ping it however the MTR results below use ICMP Time Exceeded which they haven’t blocked.

                                        The traffic in terms of geography follows this path for me:

                                        Hops 1-2: Maidenhead (our datacentre)
                                        Hops 3-4: London (our POP in telehouse east, peering with HE)
                                        Hops 5-7: New York City (HE)
                                        Hops 8-11: Dallas (It would appear softlayer peer with HE also, so it’s actually a pretty efficient route in this case)

                                        66.228.118.51:

                                          I’m looking at a move to a new datacenter not load balancing, interestingly preliminary results are better results from from their Seattle datacenter which is unexpected…

                                            Care to post your results?

                                              The results I got are pretty normal for Dallas, unless you’re moving to the UK there won’t be much difference for UK visitors.

                                                  So far average responce times are ~40% less from Seattle than Dallas…

                                                    When you’re talking distances like this, especially for streaming etc then jitter rather than latency is the biggest problem, although it’s usually only protocols like SIP for VoIP etc that are affected.

                                                    Almost all transit from the UK to the US will go via NYC, so the closer you get to NYC the better, when you jump to Dallas expect at least +30-40ms on latency.
