Think your Internet Service Provider (ISP) is messing with your connection performance? Now you can find out, with Google's new online tools that will diagnose your network connection.
Google's broadband test tools are located at www.Measurementlab.net. On that page, you'll see an first icon that says "Users: Test Your Internet Connection". Click that, and then you'll be taken to a page where there are three tests available, and two more listed as coming soon. However, out of the three available tests, only one of them is fully automated and easy to use.

Site Is Down or under heavy Traffic load when I posted ? Confused

Not known if there is direct access from Googles Site yet?

More info here

PS The Numbers may be Difficult to Interpret
And may be due to the Traffic Loads on the ISPs Servers

I have found out how to bypass the site and get direct access to the additional Servers for the Basic test
http://e2epi.internet2.edu/ndt/ndt-server-list.html
Use the Lower list and Beware there is a Lot of demand on these links (try several)

Its all in the Time Zones, the American time zones should be accessible Before 9AM site time
there is No way of jumping the Line as with many servers(Depends how many requests they can handle) No Mirror System in Place
IE If a Server is "Busy" The Request is passed on to a server that is doing nothing.
If they Put you in a queue then Look elsewhere if the Time given seems Long
Some servers were Non-OP returning 404 errors Frown

I got on the CERN Server in Switzerland with Little delay
http://ndt.switch.ch
Unknown what it says, this is what it returned
Anyone care to Interpret? Roll Eyes

I just did a retest (same Server)
and clicked Statistics
and This was generated NOW I am Confused

There were 25 packets retransmitted, 109 duplicate acks received, and 131 SACK blocks received
The connection was idle 0 seconds (0%) of the time
C2S throughput test: Packet queuing detected: 2.30%
S2C throughput test: Packet queuing detected: 84.15%
This connection is network limited 99.67% of the time.

Web100 reports TCP negotiated the optional Performance Settings to:
RFC 2018 Selective Acknowledgment: ON

Server 'ndt.switch.ch' is not behind a firewall. [Connection to the ephemeral port was successful]
Client is probably behind a firewall. [Connection to the ephemeral port failed]
Information: Network Middlebox is modifying MSS variable
Server IP addresses are preserved End-to-End

Don't most ISP's tell you up front that your connection will be throttled in certain circumstances? My ISP, if I download more than 2.2 Gigabytes or upload more than 219 Megabytes between noon and midnight will cut my speed in half. Back to normal at midnight, and traffic between midnight and noon is not metered.

I asked AOL Tech Support (Last year) if I was subject to Throttling and they said NO, unless there was heavy constant useage from my computer.(Downloading/uploading Programs)
Fair comment.
But the comments above say there is a "Brake" in the system somewhere already being applied
But by how much? Roll Eyes
