How many users are connected to each UBR?
How Much bandwidth per UBR is allocated per D/L and U/L
If these figures comes forth - then we could see if the network can indeed cope but maybe they are hidden away for a reason? All I know is that Before the 10mbit every hit the shores, 2mbit was pretty consistant but as soon as the 10mbit came into force - the speeds have shot down (I have a mate few doors down still on 2mbit) and also they have gone to crap for me (10mbit). If you try the same stuff @11pm onwards - the speeds are fine - could not get any closer to 10mbit if you tried. This tells me the network cannot with-stand 10mbit - simple as that !!
In fact Ill tell you what Ill do for a week or so, Ill DO a speed test from the Irish Site, ADSL Guide and from here and produce a chart showing the speeds come flying down during the day and shooting back up at night  |
You are correct in everything you say, I am aware we are all contended at the ubr, and you can test that irish site and your speeds should be good they are for me, but what I am getting at is ntl do not have one big pipe out to the internet it doesnt work like that instead they have dozens of pipes that go out to different parts of the internet. So that irish speedtest site for instance seems to have a uncongested peering pipe as it is pretty much max speed most parts of the day but other routes are abysmal, I have done things like test my speed on paul's speedtester and found that to be way above what I am getting so it ruled out my ubr. My reports are consistent with what gamers are reporting for game servers located in the same region and the source server has capacity spare galore, with user's on other isp's in the uk having no issues whatsoever.
I am seeing some improvements slowly tho on other routes, but unfortenatly there are also declines on some routes so I dont know what to make of it yet, but all I am thinking right now is that once more ntl have done upgrades to users before to their own network and underestimated the impact, it is a repeated mistake they should have learnt from.

EDIT: I must admit, thats what it used to be a year or so ago... whether that's changed now (and it sure feels like it!) I dont know?? |
Where do you get the 30:1 figure from?
Incidently BT is officially 50:1 but they have been running at nearer 20:1 for years now, contention is noticeable to the end user once you start going above 25:1 mark.
