I guess "go forward" in this context means "put on the list of work we will need to do eventually if enough people complain about it" :)

Had a reply on the virgin technical forums and they said that low speeds are down to spikes in utilisation but they arent at a level to esculate yet, 25mb on a 152mb service all evening isn't low enough?!! Crazy

My area (stoke on trent) is being upgraded in August. I signed up for 152mb last month and during the day i can get this speed no problem on speedtest.net.

Come the evening, anything after 6pm and speeds drop like a stone, down to 50-80mb/s ,

Exactly the same here in Oldham, we are also due the upgrade in August, I am assuming the disconnections of 2-3 hours a few times a week are a sign that work is being done.

Has it been changed from >90% for 10% of a rolling 7 day period?

The number you mention there was the old ntl value but I thought that disappeared post-merger?

Hmm no. Upgrades should be a single disconnection or group of disconnections, generally in the middle of the night.

Re: 152mb speed issues/ubr upgrade

WTF?! 99% util?! I'd be surprised if it was even possible to hit that level of utilisation, particularly on the upstream.

Then again I do recall once being told by VM my segment was at 90% utilisation 90% of the time, when I was complaining about slow speeds...

Yup, this was years and years ago though (~2009 I think?), I think (hope) it has changed since then.
