I have Verizon FiOS's 25 Down/25 Up service.

Needless to say, these results are pretty bad. To be fair though, I'm using wi-fi, and other people were sharing my connection during the tests.

Hey everyone, I'm really sorry for my late response. I was unable to use a computer for the past week for reasons unrelated to Verizon.

 

It appears that either your connection to YouTube is being throttled in some way or it's a congested server.

 

As YouTube uses a different codec in Chrome than Firefox, I would suggest testing Firefox (or Internet Explorer) with a few HD videos.  Chrome uses the VP9 codec, where as Internet Explorer and Firefox both use the H264 codec, so YouTube will likely fetch the videos off a different server. 

 

Another possibility is HTTPS based connections being throttled.  One simple test to check is download a large file from a HTTPS connection see what throughput you get.  One example is the standalone Chrome browser package which is served from a HTTPS connection:

Based on your above speed test, you should get a similar speed to what I got:

If this downloads very slowly at the time YouTube is having trouble playing in HD, then it's very likely HTTPS based traffic is being throttled on your ISP.  Otherwise, if you're just having trouble playing YouTube in HD, it's possible YouTube is trying to play from a congested server or along a congested path to it.

 

 

see if your speeds here on TMN are slower during the same hours. mine typically are slower by 10-20% between dinner time and 11 PM or so. it's a little worse than it was a year ago when i got on the 50 mbps down and 5 mbps up plan at Time Warner. i've noticed that it's still pretty fast in the morning up until 11 AM or so. from 11 AM to 11 PM it's spotty. one minute it's full speed, the next minute it's way down (sometimes to 60-70% of max. there must be a lot of people streaming video

I will try using a different browser, but I believe that my YouTube issues are the result of throttling by Verizon. Verizon isn't the best ISP when it comes to net neutrality-in fact, I experienced this problem several weeks ago, but was able to watch HD Youtube videos when I connected to a VPN server. I complained to the FCC, but now, the problem has resurfaced. Google's statistics indicate that other Verizon FiOS customers in the area are also facing subpar YouTube performance:

 

 

In comparison, this is the YouTube performance of the other major ISP, Cablevision:

 

 

Oh, Verizon. How I love you, how I hate you:

 

 

 

Thanks; that really cleared things up!

Are the TiP measurements averaged, or is the size of the download divided by the time the test took to complete?

It could have started slow... resulting in an overall slower speed.

If there's a large lag as the test start, or any time during... it can dramatically affect the results. You may have reached 28 Mbps but you had to wait longer than someone who's able to POP up to 28 Mbps instantly. That's reflected in your end result.

That would make sense, but I performed another upload test and I saturated my uplink almost immediately. The connection seemed pretty stable, too.

I did this test over Ethernet on Verizon's 25/25 plan. My Task Manager reported a consistent upload rate of about 28 Mbps, but my TMN result is about 9 Mbps lower. What's going on?

I'm on Verizon FiOS's 25/25 service in New York.
