 Given the large concentration of network operators present, these public interconnects are often considered critical infrastructure, and their reliable operation is often considered of national importance. Given the large concentration of network operators present, these public interconnects are often considered critical infrastructure, and their reliable operation is often considered of national importance.

 The IXP in this case is operated entirely by the commercial operator for its customers. The participants/customers have no say in how the IXP operates. However the commercial operator is very focused on customer requirements (and potential competition) which ensures the IXP operates for customer benefit.  The IXP in this case is operated entirely by the commercial operator for its customers.
