Short circuit in a three-room apartment wiring
The neighbors on top made repairs. The automatic was knocked out, clearly somewhere KZ. There is no electricity in the kitchen, the corridor and the small room adjacent to them. Soviet-built house of the 90s. The neighbor does not make contact; he denies everything.
In this case, contact the management company, let the inspectors be called in to check the wiring of you and the neighbors.
Try to carefully turn on the machine that knocked out, maybe it disconnected not from the short circuit, but from overload.
