Sky is throttling my connection to certain sites.

[MrBenjamin]

Sky is throttling my connection to fast.com and I can prove it. 

When using speedtest.net I get what I would expect I pay for 300Mb and get around 280, this is a wired ethernet connection. 

When I speedtest through fast.com I get 30Mb.

When I turn on my VPN and speedtest again through fast.com I get compatible speeds to speedtest.net.

This is irrefutable proof that sky has the ability to and does throttle connections to certain domains and services.

How is this acceptable.

@MrBenjamin It may be just a simple routing issue and not a throttling issue(what would be the point in Sky throttling speeds to a single speed test site?).

From my experience fast has been very inconsistent recently, i don't use Sky broadband and whne using fast I get speeds that vary from 10mbps to 500mbps, even on the low days I have no issue streaming netflix(which fast is part of), simply because it's a false result as speed test.net and speed.measurementlab.net both report 450+mbps at the same time.

Have to say I'm struggling to understand why any ISP would choose to throttle speed testing site and so generate more support calls....

Hi, yeah, I just noticed myself.  I upload to file hosters a lot and if I use my VPN, I uplaod a 1 gigabyte file at around 2.26 MB/s but if I don't have VPN on then it uploads at around 200 KB/s or eight times slower.

Needless to say, as soon as contract up, back to previous broadband provider.
