Future Plans
• Deployment of local nodes
– Iceland, Finland, Hungary, Poland, Russia, Switzerland, UAE
• Nodes outside the RIPE NCC region
– Objective is to improve global service resilience
– Ideally located at topologically equidistant places
– The same management model as for local nodes
– Different funding model
– Looking for 3-5 locations in Asia and the Americas
• AP in cooperation with APNIC
