Rostelecom will build underground data centers in Russia. The project provides three levels of protection: The first level is the creation of a backup site where copies of data will be saved in case of damage to the main infrastructure. - The second level is related to the transition to a distributed architecture: computing power and services will be located in several geographically dispersed sites. - The third level includes an in-depth location of data centers, taking into account the most serious threat scenarios.
