Does Plusnet subcribe to Netflix Open Connect - Super HD?

[#1]

I was just wandering if anyone knows if Plusnet is one of the ceritified ISPs that support their customers to use Netflix's Super HD service ?

https://signup.netflix.com/superhd

Well if you follow the last link it says "Your Internet Provider is ready for Super HD!" in big green box - I presume they're tracking the IP and know that Plus is configured.

Great, thanks
