Well the date adn time has passed and I have rebooted the router - indeed left the router and VDSL modem powered down for 20 minutes before reconnecting this morning and I am still getting the 40/10 speeds and not the 80/20 so it obviously hasnt been done yet.
Mine hasn't gone through either, despite rebooting modem and router. BT speedtest says I'm still on the 40/10 profile. There's a service alert on the Zen site and a post from one of the Zen staff saying that they're investigating why some regrades haven't taken place. Some folk have also lost internet connection for up to two hours following the regrade.
Snap, mine hasn't gone through either unfortunately. Date range was Wed 9 - Thurs 10 and here at end of Friday 11th, still no difference. Rebooted router many times, so I guess it just hasn't been done yet. Time for a call to support on Monday, or just wait tight?
Not that I'm too hard done too, still a very solid 37Mbps download, just be nice to see something in the 60-70 range!
