Intermittent Problem in Swansea Area

Hi there, I apologise upfront for my first post being a "Help me!" post, but I wanted to make sure what I am experiencing is not just something which can be fobbed off to being a problem with me / my PC etc whilst attempting to resolve it.

This morning, I noticed that there were some intermitted problems occuring with my connection, in that certain applications and websites seemed to be spiking in latency and were generally slow responding. I couldn't pin the problem down at the time, but after running various trace routes etc, I seem to have noticed a pattern, but am not sure whether it is actually related or something that i can fix from my end.

Some trace routes follow from various servers which I connect to on a daily basis, with explanations.


I use these news servers a few times a week and have never experiences any connection or speed problems. But today, the connection is continually dropping and speed is non-existant because of this.

Code:
C:\>tracert news.usenetserver.com

This is a server on the game World of Warcraft, which i connect to on a daily basis. The problems above are present on this trace too.

This is another server for World of Warcraft, but as you can see, it takes a different route to the server i would normally connect to. This server shows no latency or lag problems at all.

The obligatory news.bbc.co.uk trace.

Trace complete.
After looking over the results, everything seems to start acting up once the trace hits 'bre-bb-b-so-100-0.inet.ntl.com [213.105.172.234]'.
But after checking the ntl faults webpage and service line, no problems have been reported, so I was wondering whether I was the only person experiencing problems such as these.

Any help with the above would be appreciated

General info:

Network Setup: NTL SACM (Terayon TJ210) connected through a Wired D-Link DI-604
