On February 4th–5th from 10 p.m. to 2 a.m., maintenance work will be carried out on the HTM EENet backbone network at the Tartu Ülikooli Kliinikum network node. The maintenance may affect the operation of internet connections established via this network node. Backup links will be used instead of the backbone channels and external connections directly affected by the work, and brief disruptions to internet connectivity may occur during the maintenance. The maintenance is carried out by the service provider.
