View Full Version : connection problem ?
I get odd connection problem with uk websites.
I can be visiting sites ok but suddenly get "page not available".
After leaving ie for a while i can return and all is ok again.
Happens everday for past month or so.
Tried nslookup on sites and no problems.
Done the usual modem reboot etc.
Any info appreciated.
I usually only get that with this site (and no-one has explained that either) :shrug:
Could be a dodgy cache server - have you tried manually specifying another ?
Tried alternate proxy, if that's what you mean, with no improvement.

It was.
Are you using a router at all, or any form of NAT ?
i connect direct to modem (ethernet).
just been checking sites and after visiting a few all was ok and then at 12.07 gone again and still no access 12.16.
the sites are:
adobe.co.uk, abxzone.com, theregister.co.uk, nebula-electronics.com,
currys.co.uk, pcworld.co.uk.
I can visit nthellworld & cable forums + some other uk sites ok and all other sites are ok.
What DNS server's have you got configured ?
Obtain dns server address automatically is setting in ip(tcp/ip) properties.
Try setting them specifically ... I use
194.42.224.130
194.42.224.131
See if that helps ..
I'll give that a try and see if any change, although all returned to normal at 12.20 and so will probably be ok for a while anyway.

Looks like NTL DNS playing up again in that case:D

Remembering that changing your local dns servers will not make a blind bit of difference to web browsing if you are routed via the transparent proxies - since they still use ntl's.

Even through poxies
Think we need the BBK or Justanothernoob view not sure what you said is correct
how would i know if a trans proxy is in use here ?
The NTL proxies do use NTL dns .... JAN confirmed, but apparently it depends on the proxy being used.
btw, some proxies do DNS as well as web and will use their own engines depends on the proxy !
If in doubt they'll go to ntl's DNS tho
What's probably happened is the DNS processes on the cache were doing his DNS previously and they've run in to strife now that he's specified diff servers he's no longer using the redirected proxy DNS + is going to that new provider, the cache is using ntl's standard servers which are fine.
Basically the proxies DNS has broken so its' not handling transparent DNS caching properly specifying new address gets round that + means central ones used

Everyone is poxied now so its trans for everyone

Work pretty good for most too :)
i specify dns server as stated earlier and it seems to have improved but when i look in winipcfg the dns is still 194.168.4.100 which is the usual ntl, so i am confused or perhaps just misunderstanding.

try specifying a poxy in ie see if that works here (http://www.cableforum.co.uk/board/showthread.php?t=8783) could be the reliable poxy routing software
some things that are confusing me a bit:
when i check for proxy via nthell "whats my proxy" it says i am not using a proxy.
when i specify a proxy in ie my browsing speed drops by a third.
without a specified proxy i get the following result from robin walker speedtest:
1st 128K took 12313 ms = 10645 Bytes/sec = approx 89 kbits/sec
2nd 128K took 12703 ms = 10318 Bytes/sec = approx 86 kbits/sec
3rd 128K took 12047 ms = 10880 Bytes/sec = approx 91 kbits/sec
4th 128K took 12515 ms = 10473 Bytes/sec = approx 87 kbits/sec
with proxy specified i get:
1st 128K took 7500 ms = 17476 Bytes/sec = approx 145 kbits/sec
2nd 128K took 7203 ms = 18197 Bytes/sec = approx 151 kbits/sec
3rd 128K took 8156 ms = 16071 Bytes/sec = approx 134 kbits/sec
4th 128K took 7391 ms = 17734 Bytes/sec = approx 148 kbits/sec
I shall use the specified proxy for a day to see if it resolves the original problem.

NTL have routing software to the proxies that allegedly balances the load. It has been known for this software to frequently fall over.:td:
I think its called wccp software.
Obviously if you are getting better results by specifying a proxy please report this to NTL.
Who will get the relevant dept looking at it eventually .:D

It is WCCP (Web Cache Control Protocol) and is a Cisco Router Protocol, nothing to do with ntl as such.

So NTL do not use this to balance network load, but theitr tech support at Swansea think they do :confused:

WCCP runs on certain network routers and uses hashing algorithms to decide which caches transparently cache which sites.
TS are quite correct in this regard, WCCP balances cache loading.
Think PEM meant it's not some proprietary piece of software that NTL have installed, it's part of Cisco IOS just like the standard routing protocols, etc
It seems that specifying a proxy has resolved the problem (now i sussed the correct method re port 8080) so the swansea proxies are the problem.
Last time i called cable support re this they told me to delete temp internet files/re install os as the problem was with my system.
Think i'll just stick with the cardiff proxy for now.

Thank you knew you would know the answer
Having tried yet again with CS for a solution and after clearing cache/history/cookies/resetting security/ it seems that the problem is with my system as i can run in safe mode with networking and all sites work ok without specifying a proxy.
I am at present running fresh install with nowt but os and drivers.
I would welcome any pointers to probable cause, I can't suss this with my limited knowledge.

really annoying me now this, i'm in scunthorpe and have had a really poor connection for the past 2 days, no email and can only browse the web by using a non ntl proxy as the ntl proxies on robin walkers site all do not work, tried changing the dns as suggested in this topic, worked for about 10 seconds then hung again. can find nothing on the service status page except planned maintanance crap, no real answers as usual.
been at brother in laws house tonight, also in scunthorpe and he has no problems. :(
The proxy servers are listed on our site as well and I can assure you that they do work (most of them anyway). All the Nottingham ones certainly do as I use them. :)

There were a couple of threads recently about Scunthorpe problems...perhaps they've returned...

i have now got the proxy servers to work, however it's not the solution i was hoping for really, i know if i ring CS they will say my pc is the problem not theirs, i know it's not my pc. maybe somebody else in the scunny area is having problems and can verify this so maybe CS can investigate.:(
