Yandex evacuated its supercomputers amid attacks by the armed forces of Ukraine on data centers Yandex evacuated three supercomputers "Lyapunov", "Glushkin" and "Cherovanakis", the company's press service told RBC. As the company said, the supercomputers were not damaged. They have been relocated and will continue to serve as infrastructure for Yandex services and for training basic language models. In October, drones attacked Yandex data centers in Russia three times, which led to the shutdown of some of the company's services. After the attacks, Yandex began to restore the infrastructure and transfer systems to backup sites, and the Ministry of Digital Development began to look for solutions to protect facilities. At the end of October, the Ministry of Digital Development approved and sent recommendations for the protection of data centers, Kommersant reported. The data centers were divided into three categories according to importance - national, regional and organizational importance. Each category has its own security criteria. In the past, companies themselves began to create protective structures to save data centers from UFOs, but they did so at their own peril and risk. The recommendations of the Ministry for Digital Development actually simplify their efforts. The original version stated that for centers of the first category "an underground location is preferable". Earlier, this idea was publicly announced by the governor of Kemerovo region, Ilya Serdiuk. He suggested placing data centers in used coal mines. "You just have to lower the house, 10, 12-16 stories, not up, but down," suggested the official. He also recommended cooling data centers using "underground rivers". However, this idea cannot be called successful. There is a risk of flooding underground data centers, Bell writes. All the heat exchangers would have to be brought to the surface, which defeats the purpose of the very idea of powerful underground data centers. In addition, it would be quite expensive and logistically inconvenient.
