The Celebrity Equinox's second datacentre, seen here, is located one deck above the main one. This facility is half the size of the main datacentre and contains only a single rack of servers. It is designed to act as a backup in the case of problems in the main datacentre.
However, in the two years since the commissioning of the Celebrity Equinox, the backup facility has yet to be called into service. There's no automatic failover, and de Lange's IT team monitor all the systems from a central control room.
