It depends. Thinking of reliability: 
FICIX over here in Finland requires all full members to 
join _two_ switches in physically separate locations from separate
points in your own network, using redundant fiber paths. 
Result: a very reliable IX. In Sweden
Netnod has IX facilities in five cities around the country. 
AFAIK most of the traffic exchange is done over public peerings
in Finland and Sweden - very reliably.
