Just for kicks, let's try a little experiment. Head over to »www.speedtest.net
and give your connection a few tests - heck, choose several different server locations if you're feeling adventurous. When given the ability to share your results, copy/paste the URL to the test here.
Next, head over to »speedtest.centurylink.net/
and give that one a whirl and post your results.
Interestingly enough, the "Centurylink" hosted speedtest tells a totally different story than the ones hosted externally on Speedtest.net.
On my 10/896 connection, here's what Speedtest.net says I have during the evening:
»www.speedtest.net/result/2453118 ··· 8996.png
»www.speedtest.net/result/2453119 ··· 9637.png
»www.speedtest.net/result/2453120 ··· 0376.png
I've attached my CenturyLink hosted test that was done right after the Speedtest.net ones. I'd imagine Centurylink tells users to use their "official" speedtest, which is a crock of crap and is probably hosted at their headend, thus doesn't give a true picture of actual internet bandwidth. My "ground truth" web browsing and file downloading lends more credence to the slower Speedtest.net ones. What say you guys?
