Rang Virgin (150 from Virgin line) and got ?7.50 off the bill for the slow connection. Also saved ?17/month by going for 50 rather than 60 (thinking that I am only getting half that anyway) and getting new TiVo box and ditching paper bills. Worth ringing to save ??.

Ok, think I am going to go with Plusnet. They checked my address and are guaranteeing at least 50Mbps download speeds (and I'm going to hold them to that! ;)


Thanks for all the feedback and discussion everyone.

thanks for feeding back - out of interest: how do Plusnet guarantee the speed? I thought if they share the network with other providers (and ultimately going to back to BT Openreach), speeds are dependent on max capacity in the network? Might have gotten this wrong - could someone explain?

thanks

BT Exchanges do not rely purely on Battery back up. They also have Diesel Engine Sets and Rectifiers

that provide power during any outage and also to charge the batteries.


In my days as BT Power Eng.

2 50volt batteries (Open Cell) at 3,200 amp/h would be charged at 200 amps @ 16 hour rate..

Most ISP's have Local Loop Unbundling which means they have their own equipment at the BT Openreach exchange which bypasses BT's infrastructure, except for the bit where it requires the connection from your house.


However, Plusnet shares BT's connection for ADSL and Fibre.


A list of which ISP's have LLU at the Dulwich exchange is below.

Just started a new post on this but adding here too..


Keen to get some actual figures to beat Virgin Media with. I have 50Mb fibre connection and, since Feb am getting typically 1-2Mb in the evenings. I've set up a broadband speedtest for 50Mb subscribers - here's a link if you'd like to run it & have your speed measured against others:


http://www.speedtest.net/wave/79a7f9c6d803c859

I was going to mention Virgin's traffic management policy. However as this only applies to uploads on the 30MB and above packages, you shouldn't be getting these issues.

    • That's a disgusting slur against an innocent driver who was probably just on their way to drop off freshly-baked muffins at an orphanage when they had to swerve out of the way of a so-called "cyclist", and anyway traffic lights are just a Marxist conspiracy by Southwark Council to slow traffic down and force people out of cars, so we're all better off without it.
    • Frothy coffee? Not really my bag. A double espresso and a Marlboro Red? It's the breakfast of champions. The only dark drink with a creamy head which should ever be drunk by a man of my age is Guinness. I've also become lactose intolerant recently, meaning I get very impatient around milk. You make a fair point, but those legal channels are available for them to recover their repair, and legal, costs and, as I said: "It's up to them if they [Southwark] want to do that, of course." There's three or four grands worth of Cat N write-off, wrapped round a post there (more, if it's broken down for parts) causing problems. If they can't be arsed sorting that, I'm not holding my breath. Even Southwark couldn't screw their numbers up enough to make shifting the post back through circa 15 degrees more than a couple of grand, so there's a drink in it for everyone. It's a bit 'leany' just now, yeah, but I haven't noticed anyone having to limbo under it to get to Superdrugs. Or, they could make a feature of it. Pisa has made a fortune out of not sorting the underpinnings of their tower. Let's say it's an installation by someone called, I don't know, Bangsy, and it's a physical reminder that SE22 cannot deny its proximity to Peckham, Camberwell & Brixton. It's about the only thing that would get me back into The Bishop since the many dark afternoons of the soul I spent with Clarence*, the world's most depressed Weimaraner. *RIP big fella. You were always a great listener.   Come on Spartacus, don't be shy. You know exactly where the Green Cross Code Man was in 1973: less than a hundred yards away, on North Cross Road. https://youtu.be/C-XwVVMiCO4?si=rt8kQllev0t1Lgdi For some years, I found it quite difficult to go into The Forrester's after many long afternoons of the soul with Dave Prowse* (The Green Cross Code Man). *RIP big fella. You were always a great listener.  
    • Loving the arm chair speculation on here  Blimey how long before this gets spun out to be a drug dealer welding a sawn off whilst driving away from a smash and grab at the coop cash machine flipped his car and landed on a bollard type post  Where's the green cross code man when you need him ?
