I think the issue, touched upon by others, is that you don't know
whether the loss is path specific (although loss to Aussi mirroring
local is a small data point to add) and mostly whether it's protocol
Find a remote host (close to start with) and run the low bandwidth udp
iperf tests, looking for loss there. If you see loss there, then it's
likely that there is congestion somewhere along the path. If you start
seeing loss as UDP test speeds increase but before line rate then it
might be congestion and it might be some schedulers not being set
appropriately for your access type.
But pinging DNS servers doesn't give a good enough set of metrics to
chase this down.

No SLA, hence the question. Subjectively I expect that a fibre circuit to a
major provider will be delivering very low levels of loss, and very low
levels of jitter. I just don't have enough knowledge of what's actually
normal for a standard business fibre connection in central Auckland to
quantify my "low levels".
As an indication, for this month I've got peak loss of 3.5-4.5% and average
~0.08% to two different DNS servers on the provider's network. Off to an
Australian host it's a similar level, but at 26ms median rtt instead of a
