could it be possible that 'ping' (ICMP?) traffic is just getting low
priority? Are ISP's able to configure their boxes/networks so that
during peak times (when their equipment/network is getting thrashed to
death by world+dog logging on after work/school/dinner) that
non-important stuff is just given a low priority?

If it is, then I would not be surprised to see ping times go up... Who
wants heaps of people running traceroutes slowing down their
mp3/divx/pr0n downloads. :)

The important question is, does other traffic slow noticeably? Ie. Are
your games lagging to the point where you're getting smacked by 13 yr
olds on dialup? :)

I guess another way of asking this is: Are pings/traceroutes actually
true indications of network latency? Or can networks be configued so
that the traffic is 'prioritised' and they (ping/traceroute) are only an
indication of how long it takes for a 'ping' to get there and back?
(other traffic is unaffected)

Forgive my ignorance here, its been a while since I did tcp/ip
networking stuff at uni... And I never really paid attention in those
classes ;)

Get in touch with both Ihug and Telecom regarding the issue. Provide
traceroutes etc to both parties. Don't give up until it is resolved.
