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). cheers marty -- "Life's Little Mysteries.

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.

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. > And I've yet to hear how one will be credibly define or sustainably (and > legally) maintain such escalating limits.

Re: Lessons from the AU model
$quoted_author = "Andy Davidson" ; > > .. think about what happens when your customers' routes start appearing > through your MLP session as well. 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.

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. cheers marty -- You get 10 points for difficulty, but for execution you get minus three.
