So where is the server in the US? I must be co-located with the transatlantic termination.

One of the NY terminations that our traffic would flow through is 195.66.224.130 currently that is giving an average of 94ms which if I remove the 12ms to get to the UK end still gives 82 ...


And looking at your figures again, you must be in one of the London centres - so 70 ms is what I suggest for the transatlantic hop.

It is a little better than one I was using last week - San Diego to TBB was around 700ms !

Yep and that tallies with the Verizon figures. Given a home bb connection isn't usually going to be pushed through highest priority peering it would be amazing to see such low figures as presented earlier.

Anyway, I was working with an EC2 instance in Tokyo recently, and it was torturous. Even using SSH was noticeably laggy due to the huge latency. It feels like working through molasses .

70 to 80ms

So poster is not in the impossible area

I doubt many Be users live in Docklands, which ironically is a fairly bad area for broadband.

Tis true MrSaffron that the Canary Wharf part of docklands is very bad for broadband

However Be have been on the poplar exchange for some time - I was/am one of their first customers there. So I imagine Be have a fair number of E14 customers

The interesting thing with HyperOptic is that they target business/residential premises directly rather than per area/exchange

I've been moaning to BT/Virgin for many years re lack of fibre where I live - Annoyingly BT have FTTC in my area - but not to my development.

Hyperoptic have done a site survey where I live so all being well I'll be one of their first customers too

I'll feed back my expieriences once(if) connected

I average 87ms to NY (69.31.82.226) on a residential Bethere connection with interleaving. I used to be on fastpath, and average 6ms to BBC and 75-90ms to much of the US east coast. This was fairly consistent too.

Global Crossing are at 65ms for London-NY according to this recent article in the Telegraph., which also describes a new link that will shave 6ms off this.

However, the gamers will have to be able to outbid the hedge funds to get their hands on this.

At best 60ms is just possible assuming absolute minimal delays in teh equipment, perfect fibre, a perfect route &c.

The refractive index for fibre is between 1.5 and 1.6 (a vacuum is 1.0) and with the speed of light being 3x10⁸ms^-1 it gives a speed of light in fibre of (3/1.5)x10⁸ms^-1 or 2x10⁸ms^-1 The Hibernian Express cable is 6021km long - so forward and return needed for a successful "ping" assume 12x10⁶m

12x10⁶m = 6x10^-2s or 60ms
2x10⁸ms^-1

Already down to 9ms on FTTC. You're not going to see much more of a reduction on a residential network. Ping times to New York are 90ms. Perfectly playable.

TBH that could be improved on and should be, as latency to the USA from other neighboring EU countries can be and is half that, why Peering agreements here in the uk suck compared to them as does the current state of affairs with proper infrastructure for low latency / high speed bb

To be honest, I'm not sure. But it's a server set up for the game QuakeWorld, which has a few hundred remaining players mostly concentrated around northern europe. I suspect that the server admin may have chosen its location based on increasing the likelihood of having europeans play with the tens of northern american based players left.
