We learn that in the night between Thursday 14th and Friday 15th, May 2020, five booths for the exchange of telephone line and internet were sabotaged and put out of use. One consequence was a «blackout» of a part of the city (about 2000 users without connection). The following sentences were written and found in the site: «Let’s get rid of the technological cages», «Solidarity to the comrades of Bologna» (the seven anarchists arrested on May 13th for the “Ritrovo” repressive operation) and «Freedom for the prisoners».
