The server system consists of two active servers with two hot stand-by backup servers. These servers are connected to three independent major internet exchanges -- DIX-IE (formar NSPIXP-2), JPIX, and JPNAP. Number of ISPs are peering with M-Root and some of them are providing free transit service for M-Root. This configuration provides no single point of failure except for the highly reliable power supply system (with battery and generator in the case of outage of the commercial power supply) of the datacenter where the server system is colocated.
