OK I'm content that it's a capacity problem. The TBB graph appears to imply it and the latency now has also gone up.

Ping statistics for 194.168.4.100:
Packets: Sent = 100, Received = 99, Lost = 1 (1% loss),
Approximate round trip times in milli-seconds:
Minimum = 8ms, Maximum = 1363ms, Average = 34ms

The one saving grace for the day is that it's a rugby day so lots of people are getting wasted and watching the game rather than using their broadbandings, which is good given I'm stuck working.

Thanks all, I'll take this up with VM directly and having it confirmed / denied along with any applicable fault references. I do not expect it to be fixed until the network overbuild and DOCSIS 2 upgrade as there's very little point.

EDIT: By the way just to clarify distances that DNS server is a few miles away at the RHE:
