speed loss

[Happy Surfer]

hello everyone im getting really d/l speed today, just done a bt test and only got 1400k whereas normally im always on 6400kish speed.just find it strange that it not even peak time and speed is poor(compared to the normal great standard

[Rik]

What profile did your BT test give?

[Glenn]

The World Cup will be taking a lot of BT's bandwidth at the moment.

[Happy Surfer]

bt profile is 7150k

i understand the world cup being on and some people watching games on pc at work etc but the speed reduction is terrible, videos take donkeys to load, and browsing slow too, i understand some people only have 1-2meg connections at best anyway but when you are used to 6.5meg on a regular basis reguardless of time of day its hard to accept.

[Rik]

It's hard to suggest any other cause. IDNet have bought in extra bandwidth to allow for the world cup, and so far their network is coping fine. I'm not seeing any speed issues here, so it suggests a problem local to your exchange.

Do a couple more BT tests and let IDNet have the results, they can check the line for you.

[Happy Surfer]

ok thanks rik will do, how do i contact idnet with the results?

[Steve]

Just copy and past the BT speedtest results into a text file,then when you've got a few email them to support@idnet.com

[Maiku]

Not that its going to help you, but I have the same problem, down from my usual 800k/sec and a bit to about 50k/sec. Thats with exchange priority lol.

I thought something had chopped my telephone line or somthing, then I had a look in here, totally didnt think about the World cup taking all the bw.

Its painful, just like those buzzing trumpet things they play constantly around the matches.

England will probably be out soon tho so the speeds might pick up lol

[Glenn]

My own line is down to sub 1mb speeds

[Simon]

The tennis starts soon as well. 

[Glenn]

Tour De France too

[Simon]

We might as well give up! 

[Rik]

The frustrating thing is that I know IDNet have bought in sufficient extra bandwidth so their own network can cope, they have to pay for it for three months, so it's an expensive option for them, but if BT don't match their effort, it's all for naught.

[Glenn]

I tried to do a speedtest yesterday, but as ever, it fails on my line

Mine's down as well now, it was 6.92Mb/s just after 8:00am, now it's down to this: - 

[Gary]

Using Speedtest which I don't think is that reliable all is still ok here, even though pings are well off what they are when I test them, and I don't believe my speed either on this test either, but its not showing any major slow down like yours Ray  I am guessing you are ADSL 2+ by the upload speed.

[wecpcs]

Mines all right "Jack pull up the ladder".  





Edit: Image code sorted

[Rik]

My pings are OK, but I'm seeing a 10% drop in throughput.

I'm on home Supermax, I think it's exchange contention, Gary, my exchange has had red VPs for several months and it seems BT aren't in a rush to do anything about it. It's only a small rural exchange with about 1600 subscribers.

[ST Driver]

My connection is that slow normally that I don't see any difference sub 1meg

Steve

[Rik]

 

[Glenn]

Since the problem at Ilford 2 weeks ago, my sync has dropped from 3.2 - 1.8mb 

[Rik]

That's odd. What's your noise margin doing?

[Glenn]

9db, it was happy at 6 - 3db beforehand for about 75 days, no resyncs etc, I only rebooted it to see if it was a local problem 

[Rik]

Check in with support, Glenn.

[VaderDSL]

Can't do anytihng on my connection at the moment Can't even watch a tutorial video on youtube.

Am usually over 10mbps and this week have been at :



My sync has dropped from 12 down to 9 as well but SNR/noise is rouglhy the same.



Have done the usual restart, unplug for half an hour etc. Can't wait till the stupid world cup is over means it wont be long till a real sport (Tour de France)

[Rik]

Sync drops are always a local issue between you and the exchange, have you tried from the master socket?

Overall, there's a clear 'World Cup' slowdown affecting most people. IDNet have laid on extra bandwidth and their network is coping fine, but BT's backhaul and local VPs seem to be struggling.

[Ray]

I'll second that, Rik, I'm down to 1.19Mb/s now. 

[VaderDSL]

Yeah it's definitely local congestion/world cup related (although is there such thing as congestion on WBC/LLU?), well at least I can distract myself with the sound of a thousand bees if I turn the football on.

I know the feeling about being a small rural exchange , Ray. Saying that we have about the same number of users and somethings happened our end decrease ping times buy 12s so there is hope it all might get better, maybe  BT are now looking at the smaller exchanges a bit more

Strangely, when I got home last night, the nm was at 12db, I resync'd to 2.3mb

[Rik]

I've noticed a drop in NM of 1db in the past week (no resyncs), so I'm guessing that it's down to increased cross-talk.

Considering this is the worst world cup I have seen.

[Rik]

Part of your problem is that you've had a low sync event and that's reduced your profile to 3000k. For that profile, your speed is fine. Do you have an NTE5 master socket, so that you could connect the router to the test socket behind the faceplate?

[Rik]

I've spoken to support. DLM records suggest that you've had the 3k profile since March, but that may be because they haven't collected all the data (it takes a resync to trigger a DLM record). You do, however, seem to have had a series of resyncs on June 14, 9 in a matter of minutes. That would certainly account for the current profile.

Move to the test socket, if you have one, and give it 72 hours. If things haven't improved, then let support know and they'll ask for a manual reset of noise margin, which should trigger a profile change.

Interleaving has been turned on as a result of the recent resyncs, which will, in part, account for the ping issue.

[crynshame]

Thanks Rik. Broadband is connected to NET5, will give it till Monday hopefully things will have improved. Thanks again.

[Rik]

You need to remove the face plate and connect to the test socket which will be revealed. That eliminates any issues with your wiring (including a faulty faceplate).

[crynshame]

Ok Rik. Here are the test results from the test socket from BT:

I'd not expect anything to change immediately, you need to leave the connection there for 24-48 hours and see if the router drops sync at all. Also, keep an eye on your downstream noise margin and see if that varies much. Routerstats can help with that:

Oh dear, not only is the sync and profile down from what it usually is, there's not even an ounce of decent speed for the one I do have. I hate BT and I hate football.

[Rik]

Don't we all - well most of us anyway.

[T_M_D]

My speed has been going up and down in the last 30 minutes. 0.4, 0.8, 1.02, 1.99, 1, now running at 2.8 so it looks as if it is on the up again. I tend to get consistent speeds of 5-6 mbps so the sudden downturn was quite noticeable to me.

Hopefully, the speed will continue to rise now the England match is over.
Tina.

[Rik]

Hopefully, Tina, I was running at 1/3rd speed during the game. 

[Rapier Racer]

I appear to be running at the usual speeds again, how long is this nonsense on for, gah.

[Glenn]

A couple more weeks I'm afraid.

[ogster]

I was getting 0.5Mbps up and 0.5Mbps down this afternoon. With "exchange priority". This is on a rural exchange.
Normally 6-6.5Mbps down and 0.5Mbps up. Everything is back to normal now.

[T_M_D]

Hopefully, Tina, I was running at 1/3rd speed during the game. 

Yes Rik, mine is back up to over 6 mbits again. Fell asleep for a while there, but just done a test and it is fine. I will try and schedule my online needs around the football I think. I wonder if Wimbeldon will affect it as well... I noticed Sky TV was even slower than it usually is ('bout time they did something about that) when navigating around it during the match. At least us IDNetters could get on the net, I bet many users of other providers couldn't get on at all (02 Access users spring to mind, unless 02 has finally sorted that issue).

Tina.

[Tacitus]

....... I bet many users of other providers couldn't get on at all (02 Access users spring to mind, unless 02 has finally sorted that issue).

Looks as though iDNet can't win.   

[T_M_D]

Looks as though IDNet can't win.   

I think it is unfair of people of any broadband provider to immediately blame their provider when BT has such a huge influence over the infrastructure. Users should look at the overall picture, such as consistency of speed and service delivered over a period of time. IDNet is the only broadband provider I have had that has given me consistent broadband speeds. I go on the net with confidence knowing that whatever time of day or night or weekend it is, whether school holidays or some other period of time when the net is generally congested, I get a good consistent connection and speed. My exchange is not the greatest, but I still get good speeds.

Today is the first time I have experienced my speed dropping and it was only whilst England were playing today, it quickly came back up to speed once the match was over. I am sure that it had nothing to do with IDNet and everything to do with BT's infrastructure.

I am sure that IDNet does sometimes have issues, but from the evidence I have seen, IDNet is proactive in identifying and resolving any technical issues. I would be one of the first to give IDNet a hard time if I I believed they were not providing me with a service I expect, but I would hope that I would make sure first of all that it was indeed IDNet's fault if there was a problem and that I had given them a fair chance to sort it out over a reasonable period of time.

[pctech]

I think BT deserve a right royal roasting from ofcom over the way their infrastructure has performed during these peaks.

If they are not capable of running the 20CN and 21CN networks that constitute the national carrier networks then they need to be nationalised.

A lot of ISPs have added extra capacity in anticipation and say their networks are holding up well so why can't BT?

[Rik]

Looks as though iDNet can't win.   

They never can with him. 

[Rik]

A lot of ISPs have added extra capacity in anticipation and say their networks are holding up well so why can't BT?

See:


http://www.thinkbroadband.com/news/4282-can-the-uk-broadband-network-cope.html

[Glenn]

To me if the ISP buys the extra capacity from BT, and they can't deliver on thier backhaul, BT are in breach of contract.

[Rik]

You would think so, wouldn't you. Anyone want to bet the small print gets them off the hook?

[Tacitus]

They never can with him.  

AFAICT he is on the Brightlingsea exchange.  Very nice part of the world, but I doubt very much whether it ranks on BT's priority list.  And, given the size of the place I can't see any LLU operators rushing to fill the gap.  

If it's that important his best bet would be to move further up the coast to Clacton where he could at least get C&W LLU.  Otherwise he's into leased lines which are not exactly cheap, even assuming BT would provide one.  For a small business it may well be unaffordable.

[Lance]

AFAICT he is on the Brightlingsea exchange.  Very nice part of the world

That's not quite how I would describe Brightlingsea!

[Rik]

I'll leave you Essex boys to argue amongst yourselves.

[Tacitus]

That's not quite how I would describe Brightlingsea!

I must admit that my experience of Essex is limited to Colchester, Wivenhoe and, the Clacton to Frinton area of the coast, which I've always thought of as some of the better parts of England, if a bit featureless compared to round here. 

Given Brightlingsea is in the same part of the world I had this image of it as being a small but pleasant area.  Just goes to show.  If it's that bad and the broadband is no good either, then it's an even better reason for him to move....

PS Rik:  I'm a Midlands lad, but I had a relative who lived in Holland on Sea.  I don't think we ever had any Donald Russell beef but she certainly used to put on a spread whenever I went to stay.  Sadly she died about 4 years ago.

[Rik]

East or West, Tac?

[Tacitus]

East or West, Tac?

I'm considered to be from the West Mids, since for some reason people think I have a trace of a Brummie accent.  Never understood that since I'm nowhere near Brum even though I spend a fair amount of time there.

Mostly in the Apple Store 

[Rik]

 

We tend to fall somewhere between the East Midlands (rugby), East Anglia (broadcasting) and the SE - all others. No wonder I get confused!

[ogster]

To me if the ISP buys the extra capacity from BT, and they can't deliver on thier backhaul, BT are in breach of contract.

Trouble is ADSL is a very contended service, 8Mbps is a maximum, the guaranteed levels are very very low indeed. If everyone tries to use it all at once it breaks. BT need public pressure to increase capacity and reduce wholesale backhaul prices.

[tashtego]

A couple more weeks I'm afraid.

Nah, it'll be all over on Sunday. Bandwidth will be back to normal on Monday 

[pctech]

Thankfully most of the decent ISPs don't but their transit from BT and use decent providers like Cogent, Sprint and Level 3, shame we cant exercise a choice of carrier to get our traffic onto their networks isn't it.

[Technical Ben]

I saw an interesting comment on the Think Broadband article.
Use P2P to stream the video. As it seems the congestion is at the Core, so if you re-route the feed between neighbours, you take the strain off the centre of the infrastructure.
For example, streaming to house no 1, takes up one line, and one amount of bandwidth from the VP. Then route that back and forth from the local exchange to houses 2,3,4 etc. You get a bit more exchange congestion, but the rest of BT does not die in the process.
Not sure if that would work though. (Apparently it was unicast that's no good, and multicast is?)
[edit] This is one of the goals of Google and their shard technology and "server farm in a crate" that they want in every exchange. It would allow streaming/file downloads from the local exchange, freeing up the backbone of the net when you get a large demand.

[Lance]

I must admit that my experience of Essex is limited to Colchester, Wivenhoe and, the Clacton to Frinton area of the coast, which I've always thought of as some of the better parts of England, if a bit featureless compared to round here. 

Given Brightlingsea is in the same part of the world I had this image of it as being a small but pleasant area.  Just goes to show.  If it's that bad and the broadband is no good either, then it's an even better reason for him to move....

Well, I might have been overly damning - Brightlingsea isn't too bad, but I don't think that I would make an effort to go there. I live in Colchester and have already been to Brightlingsea and back after dropping the other half at work.

Frinton is nice but in my opinion the nicest areas around this way are away from the coast. Just a few miles up the road from here is Dedham and Flatford, bang in the middle of Constable country.

[pctech]

Hmmmm

I'm skeptical about this because an ADSL connection is a Layer 2 Tunnelling Protocol (L2TP) connection between your router and your ISP's edge router so it just 'sees' the one route so the traffic will be handed off to the ISP network (most have only one or two Points of Presence) and then routed according to the routing policy of that ISP for the destination network.

BT OTOH have regional POPs so for example in MK a customer's traffic gets handed to their POP in Bletchley so if there is someone else on BT subscribed to that stream it should in theory stream from there thus reducing the load on the rest of the BT network but it is likely others from other ISPs will be subscibed so it is unlikely to work as cleanly as that.

Thanks glen. Have just completed another speed test:

[Steve]

Unfortunately Murray's playing tennis now so BT congestion is a possibility, the router stats look fine but why is interleave on? You have a short line with a full sync I can't see why you should need it.

[camdave]

Download speed is not that important to me, mainly internet and emails (no games etc.), but I do keep a watch on it. Probably comes from being a Pipex customer for ten years!

However, speeds today are all over the place; between 5.8 mbs.which is normal to as low as 1.8 mbs. I live on the Herts/Cambs borders (01763)
If there is no improvement tomorrow I will follow up on these boards.

[Glenn]
