Friday was up/down and whenever i've checked all weekend it's been at best 3.5Mbps but mostly between 1.2-2.4Mbps when i've been watching. It'll be interesting to see what pattern emerges tomorrow when AA look at the data.<br /><br />Exchange is EACLE for anyone interested...Richwhttps://www.blogger.com/profile/00069742593452288784noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-88437899064935086872011-11-25T08:45:22.754+00:002011-11-25T08:45:22.754+00:00Has the sufferer written to his MP and get him to ...Has the sufferer written to his MP and get him to write to Chairman BT for an explanation?

We had these issues and within three months had switched to a provider that buys the elevated product with gives us nearly twice the upload speed and priority on the VP so we don't see congestion anymore however i do feel a little mean when downloading at 8mbit as i know there will be the other 690 brodband users clunking along with ~12mb! The problem is though these people arn't hugely technicaly clued up on how btw's network works and will be with a isp that couldn't car less if they see congestion like bt retail,orange ectAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-31934819767152088842011-11-24T16:40:46.750+00:002011-11-24T16:40:46.750+00:00Useful, thanks.

In turn, when this link congests, the ISP has to pay BT to get it upgraded.<br /><br />Practically, there are exchanges where fixing congestion is "too expensive", and BT try not to fix it. 21CN makes this better, by making big chunks of capacity cheaper than any 20CN capacity, but if you're in a 20CN only area...Simon Farnsworthhttps://www.blogger.com/profile/15190608047563530091noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-61730183444113702972011-11-24T14:50:57.829+00:002011-11-24T14:50:57.829+00:00Any chance you could name the small village in que...Any chance you could name the small village in question as we might then be able to investigate a little further?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-13483900613813501362011-11-24T14:36:38.252+00:002011-11-24T14:36:38.252+00:00Richw, plan is to try and fill the line and get BT...Richw, plan is to try and fill the line and get BT to admit that the link is full - or explain why a non-full link has loss and latency.RevKhttps://www.blogger.com/profile/12369263214193333422noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-86431759872017973962011-11-24T14:10:30.400+00:002011-11-24T14:10:30.400+00:00As the owner of the line in question it's a to...As the owner of the line in question it's a total farce, especially when most rural lines struggle due <br />to line length for this to happen is just a huge also in the face.<br /><br />AA have been brilliant with lots of Updates and really leaning on.<br /><br />Second time this has happened now BT really need to sort themselves out.Richwhttps://www.blogger.com/profile/00069742593452288784noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-70256049087551318392011-11-24T12:41:23.901+00:002011-11-24T12:41:23.901+00:00Aren't "consumer" ADSL lines rated a...Aren't "consumer" ADSL lines rated at ~50:1 contention, or has that number gone away now?<br /><br />By my calculations, this exchange is running at more like 300:1!Robert Chipperfieldhttps://www.blogger.com/profile/10449260824649707883noreply@blogger.com
