ISP throttling stream speeds?

xenonlul Jul 14, 2013 02:56PM PDT


Suddenly the streams I proactively watch are stuttering really badly on 720p and quality above.

I've tested out several steams and I'm getting the same stuttering video results on high quality so it can't be on the streamer's end.

Due to some additional unnecessary YouTube stuttering/buffering, I've come to the conclusion that my ISP is throttling my video/live stream download speeds.

I have Verizon FiOS 85mb/s down + 35mb/s up so my internet should be able to easily handle 720p and quality above.

So... how do I figure out whether or not I'm being throttled by my ISP or if it's the Twitch servers?

Well, we haven’t changed anything major on our side, so if you all of a sudden have huge lag issues, it’s likely to be your ISP changing routing or ‘shaping’ traffic. You may want to check that you don’t have any programs such as Pando Media Booster that can be carrying data in the background.

Aaron Clay is a liar. Non-partner channels are throttled, which is really cut slim especially when they keep trying to host tournament events they arent able to handle. I dont care about commercial channels.. and I dont care about all the stuttering packets they try to hand out.

No, we do not throttle non-partners. They’re treated exactly the same in our network as any other channel.

I also have FiOS 60/35 and noticed severe stream problems, I think they are throttling.

I'm on FIOS 150/60 and I've also noticed this... I switched services because of this problem
