In Sweden, the reason to not choose NetNod (and to go with the smaller
exchangepoints) is price and only price. No swedish ISP I know of has
stated that the fact that the Stokab fibre is bought by the IXP and not the
ISP is a problem per se. Some might have a better wholesale deal than
NetNod has but that is still just about price.  

The alternative IPXen were started for two reasons, 

1. Price. At the time the first one got going NetNod was running OC48 SRP
as its fabric. (Anyone remember that technology?). The price of SRP
technology was simply too high for many small players, and required Cisco
gear, etc. 

2. Convenience and reduced marginal cost, ie. #1 again. Since the first
alternative (SOL-IX) was and is distributed, really small ASes could join
for the price of a patch cable and an interface.

The fiber paths into these facilities are national security issues. Expect
them to be guarded accordingly (as in running them in specially blasted
tunnels 30-60 meters down in the ground for the last aggregated path to the
facility). I have not experienced more unpredictability nor more outages
because Netnod buys the cable than when the ISP does. Same cable. And
Stokab does indeed know where the cables are.

Just because you know where the cable is the backhoes won´t find it?
