Air traffic in Italy is being disrupted on Friday morning by an outage in the air traffic control data network. Service provider ENAV has restricted available capacity since 06:00 and says it rules out malicious activity as the cause.
According to ENAV, the problems were discovered overnight from Thursday to Friday. They affect the national network used to transmit data for air traffic control. The organisation reported on Friday morning that technicians were investigating the underlying cause. The statement consulted did not yet give a time when the network would be fully operational again.
Initially, contingency systems were able to absorb the impact. According to ENAV, this allowed air traffic to be handled at normal capacity until six in the morning. As the number of flights increased and the network problems persisted, the organisation decided to allow less traffic. According to the air traffic control provider, the restriction is intended to ensure operational safety.
The ANSA news agency reported severe delays to air traffic across the country on Friday morning. This makes the outage more than a technical problem behind the scenes: it affects the operation of flight schedules. However, the national reports consulted contain no total number of affected flights or passengers. Nor do they make clear how many flights will ultimately have to be cancelled.
The effects are being felt at airports in Milan and Bergamo, among others. ANSA reported disruption there and referred to a warning to passengers that both departing and arriving flights could be delayed. Radio Lombardia named Malpensa, Linate and Orio al Serio as affected airports. The reports provide a regional picture, but do not constitute a complete assessment of all Italian airports.
The capacity restriction means that ENAV can temporarily handle fewer aircraft in Italian airspace. The statement does not indicate a complete closure of that airspace. Nor does it announce a general halt to arrivals or departures. This distinction matters when assessing the scale of the disruption: reduced capacity can have different consequences for individual flights, while the national service continues in part.
On the cause, ENAV distinguishes between what has been established and what is still being investigated. The organisation has located the problem in the data transmission network and rules out malicious activity. That exclusion is a statement by the service provider concerned. The sources consulted contain no separate technical investigation report against which that conclusion can be independently assessed.
For travellers from the Netherlands, the outage is relevant because of the disruption to Italian air traffic. The precise effects at Schiphol could not be separately established using the public sources consulted; we therefore give no figures for delayed Dutch flights. Nor can these reports establish when the full flight schedule can resume normal operation. That will require new operational updates from air traffic control, airports and airlines.

Editor's note
The outage and capacity restriction have been confirmed by ENAV and current Italian reporting. The technical assessment comes from ENAV; the scale, restoration time and specific effects at Schiphol have not been established.Sources
