Since 10:30 there have been nationwide connectivity problems with our A1 wholesale lines. The cause is a connection fault in the data handover between A1 and an alternative provider. A fibre-optic connection appears to be interrupted. The technicians are working at full speed on resolving the problem and, in addition, on an alternative solution.
Update 15:00: due to a fire on Vienna's Floridsdorfer Brücke, fibre-optic lines were severely damaged (https://wien.orf.at/stories/3359189/). The fire brigade's incident command names Monday, 22 June 2026 as the possible access date to the damaged infrastructure. The technicians have been working since the morning on alternative routes and hope to restore access as quickly as possible.
Update Saturday: no new information available yet

Update 21 June 2026 19:00: the lines are expected to be made available within the next few hours.
Update 22.6.2026 16:00: Authorities expect to inspect the premises in the bridge on Tuesday. The current access situation is the same as that of the alternative route for internet access.
Update 23.6.2026 15:50: The authorities have now given the go-ahead for tomorrow, Wednesday, and further steps for repairing the fiber optic cable can only be planned tomorrow after the damage has been assessed.
