I am with Zen on Fibre Unlimited 2.
I am at 48/6 speed wise. Couldn't be happier with the service.
Out of interest I did a broadband check today and the speeds have updated to 65 down and 18 up.
Is it possible that Zen can increase my profile some way so I get the updated speeds? I don't know how VDSL works, for example on ADSL you could re-sync by resetting your modem and it would update to the latest speeds. Is this possible with fibre? I am not talking about interleaving etc.
