About this IXP

Data last updated January 2026

Capacity at this IXP

681 Gbps

Cumulative port speeds of all IXP members. This shows the potential maximum traffic that can be exchanged at this IXP at one time.

Membership and capacity

The size and strength of an IXP is determined by a combination of how many members it has, and the total capacity. Larger networks tend to bring more capacity, which can benefit all members.

Members peering at the route server

27 / 43

The route server is a central hub that makes it easier for all networks to peer without having to create individual agreements with other members.

Members using RPKI

41 / 43

members at this IXP use Resource Public Key Infrastructure (RPKI), a security measure that helps ensure traffic is routed correctly. A member is counted as using RPKI if they have at least one valid ROA.

Peering policies of IXP members

Members of an IXP can choose how they peer with others. The Internet Society encourages open policies where possible.
