[CenturyTel] speedtest.centurylink.net

Has anyone else noticed that the speed test Centurylink tech support tells you to use, »www.speedtest.centurylink.net/ often reports speeds that are wildly higher than »www.speedtest.net/ »/speed ··· ?flash=1 »www.speakeasy.net/speedtest/ »testmy.net/ ect. do? When the connection is at its very best or very worst Centurylink's numbers are similar to everyone else's, but, for example right now at 2pm on a Saturday afternoon, when I can load websites and text but videos and games are completely out of the question, there's a huge disparity between the 1.5mbps CL is reporting and the 0.2-0.4mbps that other speed test sites say we're getting from the same regions.

I've always found this odd, and very problematic when it's giving the Centurylink support guys a "good" reading (I take it they ignore ping times, which remain enormous) but in reality there's absolutely zero improvement in actual performance.

I only notice this if the server I choose if a good distance away.

Otherwise CTL's, speakeasy & speedtest all gave roughly the same amount in regards of the speedtest

CTL - 18.84 4.65
S.T - 18.91 4.13
S.E - 18.84 4.69

Since CTL's speedtest stays on their network, I would try running a traceroute to the site(s) you are having issues with & seeing if the problem is on the CTL line or after the connection gets passed on to another data carrier (when I run a traceroute to yahoo, its starts on CTL then it jumps on Level 3 communications, then to yahoo)

Never been told to use CL speed test site. But a couple of things I can think of will introduce variability. A connection should not be busy with other Internet access during a speed test. Flash-based tests are notoriously inaccurate. Speed test sites off the ISP IP network contend with other traffic from other sources. Distance to the server ...

That said, I don't see a lot of variability, except with one site.

In my case the CenturyLink speedtest

»denver.speedtest.qwest.net

gives almost the same results as

»www.speedtest.net

and

»www.speakeasy.net/speedtest

even when there are issues.

Huh, I guess it's just me. These are just now, back to back to back with nothing else open:

Centurylink:
Ping 240
Down 1.12
Up 0.24

Speedtest.net:
Ping 155
Down 0.35
Up 0.24

Speakeasy:
Down 0.29
Up 0.24

I think it's rigged too. When I'm obviously having issues(pinging my first hop(DSLAM) which is usually 8ms and I get 80-100ms at peak night hours then bandwidth on the CTL test will show 10 down and .6 up. Others will show 2-4 down and .78 up. Weird this is CTL test will show higher pings too..... and of course then want me to test with there system to see if there is an issue...

The difference is the CL Test measures the speed between you and the CL network. The test stays on the CL network and doesn't hit the internet. It shows what your connection is capable of, and whether or not there are any major issues on the CL network.

The other tests measure the speed achievable between you and the internet. Under normal conditions, these tests should all report similar results. In areas that are oversold, lack adequate bandwidth, or are otherwise congested, the other tests will report results that are worse than those shown by the CL test.

It's not rigged. It's designed to test the speed within the CLNK network where they have the ability to resolve any problem that's found.

Things like latency on another carrier's hop are very challenging to get resolved.

Tonight they want me to run some tests on the CL speedtests... which will report a high latency (over 200ms) and with down of 10 and up of .6.

If I do the same test with an external test, I'll get lower pings with lower bandwidth results...

Odd thing is I've had 3 phone techs say the latency must be over 300ms on CL tests for there to be an issue and the down bandwidth to show 6 or lower..... ALso they said Flash test are bad... though they use a Ookla flash test just like Speedtest and Pingtest (which are ran by Ookla)

During the day I can ping chicago comcast server @ 14ms with 10.11 down and .78 up. Using Pingtest.net and Speedtest.net

I'm in the middle of waiting from a local tech to call me back on a exhaustion issue the ADTRAN 3000. It can hold 3 dslams per the tech and he's swapped me to another slot and to another dslam... but what is consistent is the swap and DSLAM swap were done on the same 3000 unit.

The tech and CO supervisor further looked into the issue and found the 3000 at a 98% capacity at night(when I'm having issues). The 24/7 line seems like they can't see this issue on the 3000 and can only see my line hooked to the DSLAM... that's from my end.

It's one of those things I gotta keep bothering them about cause if I don't it will just fall through.

If I go home tonight and do those tests and they come back "OK" on their speedtests I wouldn't be surprised if they would just close the issue saying everything is fine.

I'm at the point at night I can't game cause I'm pinging 200+ and I can't stream anything at high quality due to the issue. Netflix will run 1 bar quality. I used to have no issue running it at anytime of the day and it would be running HD. Youtube - I have to run things at 360p in order for it to load without buffering every 10 seconds... usually I can run 1080p with no issue.

I have issues like this that are simple in my mind to fix and they are the ones that win this

I don't know if I'd call it rigged, but it definitely shows speeds that are much, much higher than anyone else is showing for me. Like Oomjr, I can barely run Youtube videos or download the latest iTunes update when CL is showing me at full speed, but it makes more sense when I look at other speed tests and they say I'm only at .5 or .6mbps.

If nothing else I might argue that, at least for the month or so I've been having major issues with my DSL, Centurylink's internal network numbers are completely divorced from the reality of what I actually experience trying to use the internet day to day, while the other sites seem to return numbers close to one another as well as the speed at which I can download files.

These are just from today, back to back in this order:

Centurylink: .56 Down
Speakeasy.net: .22 Down
Speadtest.net: .17 Down
Broadband.gov: .099 Down
Centurylink: 1.12 Down

Last night I did some more tests to send to Centurylink and my speedtests were all about the same results. So I'm not even sure anymore.

Give us some trace routes. CTL can't control anything outside of their network. I will also note that 2 of the 3 examples you've given (iTunes, YouTube) are notoriously slower during peak internet usage times.
