Hi,
Yeah I'm fairly sure it is just saturation on the upstream, but every time I've phoned up they've said its fine .... I think NTL's idea of fine is perhaps different to my own, however.
What is NTL responsetek, sorry?
Someone from NTL tech support tried telling me that the UBRs dont prioritise ICMP traffic, so ping results are not a good indication of the connection/latency. This would all be very well, if UNIX traceroute didn't use UDP! Plus, I think if a router is struggling to respond to ICMP whatever QoS level its given, it's probably being overloaded?
If someone from NTL could have a look at my UBR (ubr01horn-ge02.inet.ntl.com) and give an honest opinion on the upstream usage, I'd be really greatful.
Cheers
