Backbone Network

Network Operation Centers (NOCs) linked by high-capacity high-speed digital lines comprise IIJ's backbone network, the largest in Japan. Each NOC is located on premises protected by uninterrupted power supplies (UPSs), air conditioning, fire-fighting equipment, and a rigorous building access control system. IIJ's high quality connection service is further underpinned by our world-renowned network operating and network monitoring expertise.
