I don't think any IXP can become a significant player on the Internet  
today by only attracting participants from the country in question.   
The Internet is not bound by political borders.  (Usually. :)

I'm glad to hear the fibers seem to be stable.  Past performance is no  
guarantee of future profits and all that, but it is good to know care  
has been taken in the past.

As for the blasting of tunnels and national security angle, this is an  
IXP, not nuclear missile launch control.  It should not be your only  
vector to get bits from point A to B.  And if it is, then you have a  
larger problem than worrying about the facility withstanding physical  
attack.

And no, attaching to multiple NetNod nodes is not a solution, since  
only Stockholm has a large number of participants.


End of day, an IXP is not some magical thing.  It is an ethernet  
switch allowing multiple networks to exchange traffic more easily than  
direct interconnection - and that is all it should be.  It should not  
be mission critical.  Treating it as such raises the cost, and  
therefore barrier to entry, which lowers its value.
