NTL broadband not loading some sites

landmonster

I've got NTL broadband and I'm having some problems with certain sites.

For example, on one forum I use if someone posts an image from imagevenue.com I can't see it, even if I go to the direct url but I can see the imagevenue homepage.

Also, http://www.podcasting.ie/ does not work for me. I get an error saying 'connection interrupted' in my browser but that site does work if I try it through a proxy.

I can't quite put my finger on the problem because it seems to be fairly random . Just wondering if anyone else has noticed anything.

I'm not on ntl but podcasting.ie is taking ages to load. Could be their end.


Are you in firefox? I think you may have blocked images from imageavenue. If so, you can unblock that by going to options -> content -> (image) exceptions and removing the site.

It would be helpful if you can tell us a bit about your set-up: Operating system, browser.
Have you tried to ping those sites, check wheter other protocols (no HTML/FTP) fail also.

I had similar problem before, using a linux machine. Some sites, worked very well and some others did not every so often. The problem was caused by the use of the IPv6 (new) internet protocol. It is not properly supported by many sites and or the linux stack does not tolerate that.

If you are using Firefox, try to tell it not to use it for ipv6 DNS name resolution:

go to the pseudo url "about:config", filter for "ipv6" and disable the ipv6 dns use.

If you have Linux I would recomment to disable ipv6 support all together unless you really need it. There are some other sites/forum/post that explain how. Look for "disable ipv6" on google.

I've just checked it for you on Leap and NTL.

Using Leap, it loads up in seconds

Using NTL, it doesn't load up for some reason.

Here's a tracert from Leap.

We are working on bringing the audio files into Ireland because we're receiving complaints on the speed that they're being served from Yahoo's Geocities servers.

Thanks for the heads-up.

My NTL has been slow with certain sites as well with the last few days. Google, Sky News etc always loaded up straight away, but boards took aaaages and Virgin airlines ... seem to be working ok now though.

Few other sites acting strange. Usually file sharing (rapidshare etc)

For work purposes obviously...

geeksquad

rapishare.de is not loading for more that a week or so ...

Dodge

rapidshare.de is back working for me but rapidshare.com is down

MiloFoxburr

podcasting.ie wouldnt work for me either so I figured I might as well test out another dns server

So I swapped over to OpenDNS (www.opendns.org) and now Podcasting.ie loads fine, boards.ie loads faster as well.. Not every site I had trouble with works but it will do for the moment

-edit- Just to be clear I'm on NTL BB too

-edit2- This is actually quite a huge difference majority of the sites I visit now load almost instantly whereas before they'd take a couple of seconds (Im on 6meg..)

What is your set-up?

I reckon that if you run a traceroute as something natural is because you have a Linux or someother unix like system. If so, there is the possibility that you have dual booting with a MS Windows? Have you checked whether you have the same problems with MS Windows. If not, a NTL specific problem can be discarted.

Disable Firefox IPv6 DNS resolution is just one step. For instance, look this instructions for the GNU/Linux debian distribution:

http://www.debian-administration.org/articles/409

Some people have described that problem as a bug or inconsistency in the ipv6 implementation and changing some kernel parameter values in /etc/sysctl.conf did solved the issue. Righ now it seems that I am not able to find the page . Aparently, I'm not using the proper keywords in google.

In my case, it just affected HTTP(S) applications, ftps ssh, torrents, etc... worked fine (perhaps slow but worked not the less). Have you tried that? eg you cannot access http://www.mozilla.org but you can connect to their ftp service (using command line ftp client rather than the web browser).

regards, Db.

discretoboy

http://www.ebaumsworld.com/ does not work for me either right now...

could you give more well-known examples, web sites that would surprise very much if they don't work? e.g. www.google.com (I never had problem with this one myself when I had the issue). www.yahoo.com, www.nasa.gov, www.youtube.com .... what the heck is ebaumsworld anyway?

Running OSX but I can run Windows XP. Will boot into that and see what happens but I can't imagine it'd be any different.

Is OpenDNS good then?

Obviously it's not just me having this problem though and it looks like the problem is NTL's broadband making the hop from blueyonder in the UK. Is that who they get their connection from?

I use OpenDNS and it does quicken some sites up (or seem to anyway). Won't get me into podcasting.ie or rapidshare.com. I've also encuntered that problem with imagevenue

I've tried these sites through http://www.megaproxy.com and they open (though obviously aren't functional) so it does seem to be an NTL problem

I'm not a techie so I can't give you any more info...

I was having the exact same prob on ibb and used opendns and now yahoo and msn are back working... but boards is really slowwww

lensman

(NTL) I can connect to RS.com and other sites mentioned via proxy server only, can't access RS.com or others using opendns via router settings or pc settings.
maybe NTHell don't like the amount of data transfer from these sites & have put a block on at there end,..:mad:

Same issue as IBB then? Big server broken somewhere?

WTF folks....this is happening on BT 2mb for me all evening...seems fine for Irish sites and some UK ones, but most UK and US are 404ing.
Traceroutes are unable to resolve.

It comes and goes....router is operating normally and I've tried 3 different browsers. Did someone spill coffee on something important?

stephend2006

Ok guys, the problem is nothing to do with the dns, its the proxy.

I have been testing a number of different proxy servers, trying to access rapidshare.com and i works.

The quickest and easiest proxy solution is to go to google's language tools --> Translate webpage (enter website details here), and translate Spanish to English.

Have Fun.

yes proxys work, not much use when using flashget or idm seems like poor of no access at all to US based servers

stephend2006

Instead of using flashget or idm for downloading use reget (windows) or igetter (mac) both have no problems with proxies.

it's better than waiting for NTL to sort out their service.

Yeah, I've had the same problem with megaupload... a friend on eircom and one on esat can both access it perfectly:mad:
Have tried from my laptop and desktop pc and it's the same thing
(using the translate from spanish trick above doesn't work either...)

Dodge

Its aaproblem with a load of UK based ISPs too (its coming up regularly o various forums) One punter contacted NTL in the UK and apparently they're "aware of the problem and working on it"

We'll see

inforfun

Having problems here since December 29th. Called several times with NTL (having their 6mb package) and was promised to be called back just as many times. You guessed it... no call back.

Yesterday i was even promised an engineer as i ma 99.9% sure it is not my problem but NTL's. I guess this engineer got lost on his way as i didn't see him.
At times my connection is as it has been for 22 months, flawless. Most of the day however i get jealous of dial up users. Sites do load but i have to shave my beard between clicking a link and actually getting the web page.

If NTL is having a problem, fine. **** happens but inform people about it when they call. My patience has been tested long enough and i ll now be testing theirs by not paying my bills for a while.

yes,...RS.com & others did come back for me too but gone again now......:mad: :mad: :mad:

I am having a similar problem access some sites on NTL (home), that I can access fine on a different provider (work / mobilephone).

One of the sites I can't connect to is DogTrainingIreland.com. Yet I can access DogTrainingIreland.ie perfectly fine. Both the websites are hosted with the same US company, with the .com autoforwarding to the .ie. They have different IP's. (I look after the site).

It seemed to suddently start on Tuesday (16th Jan 2007) evening.

Am waiting on an NTL technician to not ring back :rolleyes:

landmonster

It seems to be US based sites, from what I can see, and when you do a traceroute it always breaks down at blueyonder.co.uk

inforfun

Of course i am still waiting for NTL to call back. My last cal lto them being last Friday. i was even promised an engineer... i guess he got lost.

here 2 speedtests:
A good one, where it is at its normal behaviour and the bad one, usually i have the good connection early evening, till around 9 pm. then it is back to bad.

I just cant get a single bit away here. Causing websites to time out or load horribly slow.

Im also having problems with NTL when accessing some sites, for example: bf2s.com (BF2 stats site). Stopped working on Sunday night.

Works fine through netsource.

Logged a call through the website to support 3 days ago, no response.

I've tried using OpenDNS and according to the test page it's configured correctly but the same problem exists. What's that about?

I have opendns in use as well but it doesn't improve much. I have asked a round at work a bit and i hear quite a few people complain about this problem. And they are on different providers.
I am more or less out of options. I did my bit, now it is the providers turn. Not holding my breath though.

i've had these problems since the new year (NTL max), tried OpenDNS a week back but it made no difference. a lot of the free file hosting sites seem to be affected, first to go on me was 'filefactory.com', then 'megaupload.com', followed by 'rapidshare.com'. RS came back after a few days, but the others are still just blank pages and tonight i found that 'gigasize.com' is another no-go.

i put in a call to NTL tonight and they claimed not to know of any problem with these sites. but.. the guy did ask me for the mac no. on my modem??
if this is NTL's way of reducing bandwidth abuse i think i'll be heading for the Smart alternative.

They trace based on modem macs. Its tied to your a/c. They'd ask for it regardless when reporting any BB issues.
They would only reduce bandwidth with a stream analyser that minimizes available bandwidth for P2P and BT traffic during peak hours. Because of the amount of traffic that'd have to watch and learn trends and what not, I doubt they have any constraints on bandwidth abuse.

Tonight is the first day since december 29th that i seem to have the proper connection. Whether NTL is controlling data abuse i dont know. i had a warning a few months ago but after that i did behave (was a matter of different interpretation of their rules). Since that letter i have been every month around the 40 gb data (up and down =40 gb, i assumed you had 40 gb a month download only....) so i cant believe that 5 months later they will "teach" me a lesson. Times my connection was bad was rather inconsistent as well.
Come to think of it... 40 gb per month on a 6mb line is somewhat hilarious....

RS.com, RS.de, gigasize.com & filefactory.com working for me now (NThell max) megaupload.com is not.

Still having problems. Has anyone else noticed it getting better?

today i saw megaupload and gigasize were working again.. and filefactory is still dead unless i use a proxy.
i got a return call last night from BB support. she could only suggest i lower my browser privacy settings, which made no difference.. but 'they are looking into the problem'.

and maybe they really are

speedy21

Megaupload not working for me at 3.30am - so cant be off peak.
Logged in using dial up and Megaupload works no problem - so deffo being blocked by NTL for some reason.

JNive

browser privacy settings ? these people really are clueless arent they. what in the world has browsers' settings got to do with whether NTL are able to route your traffic to a server lol.

UPC live at INEX

currently there are only 3 useful peerings up at the moment though. Microsoft, Eircom and NTL Telewest.
Looks like they are slowly getting things sorted

RIPE data shows that they have yet to switch on the BGP announcements, so might take awhile before the new routes kick in

I've been noticing the same thing.

Before X-Mas, for two days there were a load of sites in the UK I could not connect to via NTL, from one of the UK's largest hosting providers.

Running a tracert stopped within NTL.

Using alternative connections, these sites worked just fine.

Yesterday, I couldn't connect to EA.com for a while. Then it fixed itself - so I'm rather confused as to why this is happening, though I've noticed it myself.

JNive

its the routers within the NTL network either having conflicts between each other during routing updates, or just plain dodgy software being run on these systems which are either crashing/locking or causing the devices to act completely strange lol
