Fast.com is a lot slower than both speedtest.net and http://speedtest.dslreports.com/speedtest http://speedtest.dslreports.com/speedtest for me... I get 78mbps

Fast.com is a lot slower than both speedtest.net and http://speedtest.dslreports.com/speedtest http://speedtest.dslreports.com/speedtest for me... I get 78mbps on fast.com and 350 on the other two. Not sure what's going on? Maybe they don't have servers near me, I'm in Paris, France.

Perhaps that is a reflection of your provider's ability to serve bandwidth to Netflix servers?

My results were similar on DSL: Speedtest 12.6 Mbps Fast.com 13.0 Mbps But differed on LTE: Speedtest 40.0 Mbps Fast.com 73.0 Mbps

One possibility is ISP skimping on peering and transit. Had that issue with an old ISP in Switzerland.

Mine is actually faster on fast.com. About 140 on fast and 128 on speedtest. Yay.

Maybe your ISP is generally throttling your traffic but whitelisting speedtest et al to hide it.

More likely your ISP is cheating and you don't actually reach 350 outside speedtest and some other routes they make sure you are unthrottled on. Would not be the first.

  Maybe they throttle Netflix yes... I do get 350mbps on every other test and when downloading a test torrent though.

What does testmy.net show?

It likely depends where the netflix servers are relative to you versus those used by other speed tests. For example, at my workplace in a big US city, I get about ~500Mpbs down from dlsreports, speedtest.net, and xfinity speedtest, because they are all using servers based in this city. Speedof.me and fast.com are not from what I can tell and give me download speeds between 200-300Mbps.

Notice how speedtest.net selects a server geographically close to you? Well many ISPs work directly with speedtest.net (and other similar services) to ask them to put servers in their own networks, so that traffic avoids going through potentially saturated peering links. So you are really testing the bandwidth of the last mile to your house and the ISP's internal network, which is not representative of your real network bandwidth to the rest of the Internet.

  That's how it's supposed to be. Speedtest is measuring essentially that you're getting what you paid for. If you have 50/50 Fios, you're paying for a 50mbps connection to the Verizon network. > So you are really testing the bandwidth of the last mile to your house and the ISP's internal network, which is not representative of your real network bandwidth to the rest of the Internet. There's no such thing. If you were downloading a file from a friends computer and they have 2mbps upload, your connection speed will be 2mbps. How would your ISP have anything to do with that? Fast.com just measures your connection to Netflix, which is valuable if that's a service you use a lot.

    "There's no such thing." Yes there is. The Internet is not an abstract cloud with unlimited bandwidth everywhere. Your ISP runs their own network, peered with other bandwidth providers or other ISPs. You may have a 50 Mbps downlink from your ISP, but it doesn't mean the real-world usable bandwidth to all hosts on the Internet will be 50 Mbps, because your packets will be going through these peering links when they leave your ISP's network. "How would your ISP have anything to do with that?" Well, simply put some ISPs have terrible peering and/or intentionally throttle. So speedtest.net will show you awesome numbers, but in practice anything you download will be at much lower speeds. This matters, this is precisely why fast.com was built, and this is why the GGP is seeing different bandwidths when testing with speedtest.net vs. fast.com.
