On July 31, from 9 am to 1 pm, substation maintenance will take place, resulting in a power outage in buildings Ravila 14a, Ravila 14b, Nooruse 1 and Oswaldi 1. The work will be carried out by the service provider. During this time, only UPS and generator-powered systems will be operational. After the power supply is restored, we recommend that you check that the devices connected to the network are working correctly.
