Well was wondering if anyone knew how bt connects you to the net, as in servers they use, should they be local to you?

I live in lincolnshire, I ran a tracert to bbc.co.uk and is showing I head to Edinburgh, is this right?
Here is the results I get


C:\Windows\system32>tracert bbc.co.uk

Are BT having a laugh with this?
 
BT routing is fubar any more - I live in Somerset and guess how I route to get to a server in London? Sheffield? having a laugh? Once upon a time I used to route via Reading or Bletchley and had nice low pings - now I have an extra 10-15ms and get affected by traffic conditions throughout the UK... all because BT cheaped out with 21CN...

Not to mention the problems I'm having with getting interleaving disabled yet again... incompetant muppets doesn't come close.

well i was on the phone to them earlier for nearly an hour, the guy spent 5 minutes telling me to wait the ten day period, he had previously asked when my service was active which I answered the 6Th November, he went on to tell me to wait till the 16Th, I said hold on it's now the 23Rd, Muppet's is putting it politely lol.

It seems Edinburgh is my default gateway to the net,(the address is in the bt hub)(pile of dog Pooh that thing is) that doesn't seem right at all, it's no wonder i cannot play on line games anymore.

At the end of nearly an hour he said there is a fault somewhere and he will ring back within 48 hours, I really don't believe any thing will change as he had no clue and I think he just said that
 
As I understand it, it's how their network operates in the case of 21CN connections, your session is punted to a RAS at any of the major metronodes, not always geographically relevant to where you are which gets you onto the 21CN backhaul.

Unfortunately the OP is going via Edinburgh which historically is a problem node.

TBH You're pretty much banging your head against a brick wall talking to BT's support unless you can get the issue escalated, bug again not going to be a huge amount they can do as it is just how their system works.

You could try disconnecting your router for half an hour or so and then reconnect and see if you get shunted onto another node.

If you want better routing then get a better ISP, though in the grand scheme of things 10ms here and there isn't really going to make all the difference in most cases.

Code:
AAISP Be Line in Liverpool:

Tracing the route to bbc.co.uk (212.58.224.138)

10ms doesn't make huge odds - but I find the extra 300mile trip to sheffield and back - which is completely unnecessary if BT had any degree of competency - exposes me to the traffic conditions across a large part of the country.
 
Time to get a better ISP. :)

well I tried two weeks of sky hell, believe me if I could I would, where I live is crap for providers, sky, talk talk, or bt, sky gave me a download speed of O.15 Mb at peak times, at least with BT it is not as bad, but is still crap.

Someone from BT rang me back saying problem fixed, and asked me to check speed, 1.2 Mb down and almost no upload, lol, they gonna send an engineer out next tuesday, I won't hold my breath
 
You can get decent service from BTW providers, they just don't cost £10 a month - for a reason, transit on BT's backhaul is bloody expensive.

I'd persevere with BT for a while, failing that move to an ISP that might actually firstly care a bit more and secondly be better equipped to deal with getting BT to fix things.

Only have to look at how much better the competition is compared to BT's service, costs more but like most things in life you get what you pay for. I have a lot of clients now connected up with AAISP on a mixture of Be, 20CN and 21CN backhauled lines and generally speaking they are one of the best ISP's I have dealt with in recent years.
 
BT suck, I got 11ms in 2004 on 512k now I get more than double, still more than playable (when stable) but hardly progress is it?. Sometimes they may change your RAS which will increase or decrease your ping.

well I am paying a little more than £10.00, it's actually £27.99 a month, I am limited to ADSL max, so i am a bit screwed:(

Not really, all the providers I linked to on TBB are able to provide services over 20CN (ADSL Max) and for £30 a month you should be able to get something decent. Just don't execpt it to be "unlimited" like BT sell.

My parents live in Lincolnshire as it happens, they have a near enough 6Km phone line and only get 1.5Mbit sync on it, but they are now with AAISP and it has been very reliable and performance has been pretty much perfect. Maybe not the cheapest provider there though if you use a lot of data during office hours at home, but if all your use is in the evenings or at the weekend they aren't as expensive as it might seem.

It sounds like you were on the Sky product that uses the BT network. I recommend you checkout Zen and IDNet. You will get full speed and low latency 24/7.

Been with Zen for years, only ever had to call them once (and it was a local BT fault).
