Re: BS
Who was measuring geographic distances?
I was measuring network "distance" with milliseconds. I don't generally measure in geographic distance when talking networks.
I don't care WHERE the Akamai servers are in the world, as long as they are the ones I can reach fastest.
So in those terms, the ones with the lowest latency to me could be 500 miles away, while the highest latency could be on servers that are only 200 miles away. And I'm sure hoping that I'm using the "closest" ones network-wise.
I would swear I was pretty clear about that in my first post on the issue of Akamai "distance."
Did I once mention how many miles away something might be and mention that it would affect speed? I don't think so. |

said by smcallah  :said by jester121 :hehe... how far is a ms?  That would of course have to be figured from the speed of light through the media that your signal is going through, as well as the speed at which the routers and switches in between route and switch your packets for delivery. So probably not a great way to measure geographic distances, is my point. |

And again, that's only true if the path you're going on to get to the Akamai servers nearest to you is a good path.
If the peering between your ISP and the ISP it has to go to with Akamai servers is running near capacity, then you could have some TCP throttling occur.
If your speed test server is not on the same exact ISP where your Akamai servers are, don't expect them to both be 19mbps, that just isn't realistic.
Not everyone has optimal placement of Akamai servers, which is pretty obvious by the split of people that don't get the message on the HD site, and the ones that do.
Earlier today, I was being directed to Akamai servers that were very far from my ISP, about 70ms away, and I was on a 100mbit lan with multiple 10GE circuits outbound to the Internet, and I only got the 7.5mbit message
But now, the Akamai servers that I am directed to for www.thehdweb.com are extremely close, only 10ms away.
So not everyone is always optimal. Don't consider your personal experiences to be everyone's experience. Especially when there are people saying otherwise. |

If you're in the US, you're close to a server.
Latency across the US (continental) is less than 100ms. That sort of latency isn't going to drop a 19mbps speedtest down to less than 7mbps.

said by DaSneaky1D :That's Akamai's whole marketing pitch...I wouldn't think that'll be the problem with his speed results. Right, but not everyone is located close to Akamai servers. His speed tests were great, sure, but he wasn't speed testing to the Akamai servers. So again, speed is certainly affected by what path you take to get to Akamai's servers that are nearest to you. |
