Banging my head against a brick wall!!!
 

Hi Folks, ;)

I run a site http://www.phishybusiness.co.uk that is having a fair amount of problems with users unable to connect. I have done the usual things to solve it, removed graphics and reduced the overall size of the index page just in case it was that, turned on all the cache's I have etc..

Well I also got my host to do a check on the IP's that were having problems, they all turned out to be NTL IP addresses and my host has performed various traceroutes and checks etc and has com up with the conclusion there is a routing issue somewhere withing the NTL network that is causing the problem.

So I have had a couple of the members call up to see if they could sort it and basically told that there is no problem on the side of NTL - strange though that I have been reading plenty of similar reports on this forum - Anyway my problem is this..

The site will come backl up for members occasionally and they are ok to use it, with no speed issues etc, then it will die, 10 mins, 1 hour, 5 days.. there really is no pattern. I am not an NTL customer and as such cant really call up to try and get something fixed and my members ( already getting impatient, but still trying) are getting no where.

Can any of you advise where the problem MAY be, or WHY it could be happening so at least I have something to tell the people who are calling the issues in to tech support...

Please help

cheers

It's a proxy cache problem, i've just viewed your site with a non-nttl proxy fine, but it would not display using the default proxy.

Re: Banging my head against a brick wall!!!
 

Thanks Jon,

Now how do I put that in simple terms for the boys at NTL to fix without giving my members the usual load of excuses etc?

cheers

Re: Banging my head against a brick wall!!!
 

to be honest, i'm not quite sure, ther are NTL techies on here and a few other members with links to NTL that could draw attention to the issue.

What may be an interesting and revealing factor is if the people that had trouble visiting your site were from the same geographical area, which would point to them using the same proxy to access your site.

Sorry I can't be any more help.

Re: Banging my head against a brick wall!!!
 

I think they are all in and around Manchester (the ones who have reported problems)

It has been going on now for well over a week and its getting frustrating for them but more so on my side because I cant provide the service they are expecting due to circumstances I cant fix.

I will post up the traceroute done the other day for 2 of the IP addresses and see if any of the techy guys can escalate it for me.

thanks for your help so far

cheers

Hi leigh

:welcome: to Cable Forum :)

Does sound like to good old ntl proxy issue.

I can view your site fine on my default proxy on my ntl connection.


The usual fix, is to tell your browser to use a different proxy, as it's not possible to bypass the proxy with ntl.

If you tell your users to go to the following page, it has details of how to manually set a proxy to use, and has a list of available ntl ones.
http://homepage.ntlworld.com/robin.d...trancache.html
Jusr randomly pick one from the list and try it!

Cheers
Mike

Re: Banging my head against a brick wall!!!
 

Cheers for the info Mike, I was one of the forum members that couldn't access the site. Changed the proxy to baguley from manchester and it seems to be working fine now.

Re: Banging my head against a brick wall!!!
 

You must all be mistaken, the NTL proxies are perfect ;)

Seriously though, I also could access that site fine, which is a miracle as the Poplar proxies have been awful just recently, I have to refresh almost every site several times to see the page :(

Just another day in paradise...

cheers

Ian

Re: Banging my head against a brick wall!!!
 

Thanks folks, it all seems to be working ok now ( for the time being at least)

It just makes me wonder if this is such a common problem why on earth has a more stable and permenant solution not been found yet? I am on Telewest and rarely get an issue with anything, it seems to me that NTL should be doing the same.

cheers

leigh

Re: Banging my head against a brick wall!!!
 

bunglehaze I am sure many people are thinking the same as you, the only people who know the answer are NTL themselves :(

Re: Banging my head against a brick wall!!!
 

I'm on ntl and rarely (and I mean rarely) get a problem with the proxies. If it enables ntl to reduce bandwidth charges and keep my Internet service at a reasonable price then caches are fine by me.

Re: Banging my head against a brick wall!!!
 

I couldn't access your site until I changed my proxy setting, i'm on a manchester proxy by default. Loads fine on Baguley and Cardiff proxy's.

Re: Banging my head against a brick wall!!!
 

I agree that the proxies would be fine if they worked properly *and* saved NTL money, the simple fact is that for a lot of us they don't work properly - and seem no nearer to being fixed :(If NTL ever get around to matching the speeds of the other ISP's then I dread to think how the proxies will cope, they barely manage with 3 meg :(

Re: Banging my head against a brick wall!!!
 

also need to remember because of the proxies apps such as realplayer and wmp need to be specifically configured to not use the proxies, if they are not then numerous problems occur, my real player wouldnt stream at all on the default settings. Imagine the problems this causes for the thousands of novice users out there.

Re: Banging my head against a brick wall!!!
 

Sorry to drag this up again but I am hoping one of ther NTL techies can pick this up..

I am still having problems with members not being able to access the site from their NTL connections. Most have changed proxies and it works ok but others it still times out. What I need to get though is a permenant and universal fix for this as potential members on NTL cannot even access the site to join.

Can any of you advise who I need to call, on what number and the best way to try and find a solution to this problem. I am losing money through a fault apparently created by NTL and im not a very happy bunny.

there only seems to be a problem with this 1 site too. Can it be rectified by moving to a new web host or am I thinking too simply.

Any help you guys can give will really REALLY help and is appreciated.

cheers
