In confined waters like the Suez, Red Sea et. al. there is a lot of overlap.
Which makes three cables cuts in that area during bad weather not such a
stretch of the imagination.

Open waters like trans-Atlantic and trans-Pacific have less overlap with
shipping lanes but still need to cross fishing areas etc.etc. But you'd be a
little more suspicious if those sites had a similar cluster of cuts unless
there was something in common (i.e. same landing station, cuts close to
shore).

Sure it is. By knowing that no-one sharing the backhaul to the DSLAM at my
CO can afford to do line rate 24x7 makes me sleep better at night. By using
an ISP with sane limits I've never noticed performance degradation, even
during peak periods.

The wrong 2% of what?  :-)

If you want to see the flat-rate churning horde in all their glory visit
whirlpool.net.au, otherwise affectioninatly known as "whingepool" because of
the bitching'n'whining every time an ISP goes under or attends ECONOMICS 101
and brings in sustainable limits.

Simon's post pretty much sums up the kind of maths that justifies them.

Legal? What's legality have to do with this discussion?

Anyone with clue is doing community tagging on learned routes and community
filtering on advertised routes and/or as-path filtering on advertised
routes.

Anyone without clue is welcome to send me their ratecard.

This was basically setting up the next comment which was in relation to how
this situation ("my customer is now at a multi-lateral peering point I'm on")
is not really an issue as far as the bean-counters are concerned. Unless any
ratio limit you have was applicable to that customer.

Standard practice would be to localpref customer routes over peering routes.

Likely to result in assymetric routing as the customer prefers peering
routes over transit.

The customer's inbound (standard billing metric) won't be affected but their
ratio might.

it's arrogant to use throwaway lines like "address those problems" when the
reality is a complex political and corporate stoush over a former government
entity with a monopoly on the local loop.

AU should be at a stage where the next generation network (FTTx, for some
values of x hopefully approaching H) will be built by a new, neutral entity
owned by a consortium of telcos/ISPs with wholesale charges set on a cost
recovery basis.  if either political party realises how important this is
for AUs future and stares down telstra in their game of ACCC chicken, that
may even become a reality.

if only it was so easy. 

AU's infrastructure has a long been a quagmire of political fumbling and
organised chaos. 

as mark keeps trying to point out the current state has nothing to do with
the wants of the ISP industry. they all wish it was different too...
