I download that file through my transparent proxy and get 256kB/s.
I then change to the Watford Proxy "watf-cache-1.server.ntli.net" and download at 1200kB/s. Someone explain that one

Come on NTL sort it out Please

I should also Mention Im in Hemel Hempstead
Also my transparent Proxy is ALWAYS 'lutn-cache-2.server.ntli.net'

TBH tho all i do is surf using the Watford Proxy and use NNTP which isnt affected so my connections fine at moment.
I'll respond to this one even though I'm probably wasting my time again considering that my earlier post was obviously not read.

Firstly, stop stuffing FTP through the caches, they aren't there to cache FTP transfers and as you probably noticed performance can't be guaranteed. You don't download any FTP file through a transparent proxy in normal operation, they cache web not FTP.

You're a network tech (whatever a network tech is, these days means anything from a CCIE guru in charge of the entire world network to someone who changes passwords at a College) but you didn't read my link on WCCP, Web Cache Control Protocol, nor what I said about it. Just to repeat...

The only time this changes is if a cache is down, in which case the hashing algorithm will take account and split the traffic between the remaining caches so they all take a slightly larger address space each. The reason you see the same cache is probably because you are going to the same site to check it every time.

In any case, I'm not denying there might be issues with Luton caches, however for the absolute last time This isn't what's affecting FTP and gaming, for God's sake just get the signal issues fixed then start worrying about what might be wrong a bit further down the line!!!!

OK I'm really out of this thread now, by all means get the caches fixed as there probably is an issue with one or more of them, still won't resolve the slow FTP transfer issue so you'll have to carry on stuffing every protocol through a cache not intended for it, which may stop working at any time.
