Thanks - no I understand that... We have multiple transit providers today and are already present on a couple of smaller peering exchanges with an open peering policy... our experience with them has been very positive. The redundancy perspective is that you now have more paths to the same AS - and an assumption that the peering route will always be best (I know that's not always true). We of course have enough transit in case of a peering outage - would never "put all our eggs into one basket" that it sounds like some others are doing.... also, we are looking at a number of them in various parts of the world currently which adds another level of redundancy per say....

(the amsix with their many outages and connected parties that rely primarliy on it's functionality is a prime example here) internet exchanges usually are some sort of hobby computer club, you cannot rely on them to actually -work-, but when they do work that's "nice" (always make sure you have enough paid capacity to cover for it when they do not work however!) peering on only one of them therefore does not make your network more reliable in any way (it becomes a different story when you connect to like 10 or so worldwide). as for "peering" agreements, just implement an open peering policy (doesn't nessesarily have to take place over an ix, also applies to pieces of ethernet running from your network to others). those basically are contracts that force anyone who has also signed one to peer with your network, wether they like you or not (saves the trouble when you are a content provider and others do not want to peer with you because they provide content too and you are a competing party etc). -- HRH Sven Olaf Prinz von CyberBunker-Kamphuis, MP.

I can think of some but looking to develop a concrete list of appealing reasons etc. such as:
-control over routing between networks -security aspect (being able to filter/verify routes to some degree) -latency/performance
I'm surprised you didn't include "chance to pick up a redundant connection".
