First thing springs to mind is Firewall!

Secondly, could one of the lines have db noise on it, it may get worse with the data transfer..  Had this a wee while ago with a customer...  changed his pairs back to the exchange.. sorted MOST probs...   ask phone company for a PTO... (Precission Testing Officer) to evaluate the db loss on the lines !!!  ;)

NLB configurations I think are a bit sensitive..

Although not related, once we had a bad experience..We do network balancing  on the servers  not the routers...And become a nightmare for Activex controls..When you try to install the activex from the client dont work.But from a normal IIS server was OK..

I can't believe no one has suggested this already, but have you tried turning it off and on again?

I cannot log to the Telco, until I've proven a few more things,

It will go from Frontline Monkey, to DTO, then PTO

First thing springs to mind is Firewall!

Secondly, could one of the lines have db noise on it, it may get worse with the data transfer..  Had this a wee while ago with a customer...  changed his pairs back to the exchange.. sorted MOST probs...   ask phone company for a PTO... (Precission Testing Officer) to evaluate the db loss on the lines !!!  ;)

How can the firewall be related, if I'm testing directly from the router out to the Internet? The Firewall is behind the router, just in front of the LAN..

May be they use hardware style firewall (ie not on a server) .They are located before everything else

It would go

Internet > BT Network Termination Equipment (NTE) > TC703 > Cisco Router > Hardware Firewall (juniper).

So as you can see, my tests from the router, go directly out to the internet, the Hardware firewall has no involvement or control in that.

I was looking forward to proving this issue today, but had to take an emergency day off work when Maria fell ill :(

well I'd go with the suggestion of running a traceroute, it may be that the non-working sites don't have a route back to the source location ...
