Air travel across Italy was disrupted on Friday, October 16, after a technical fault affected the data transmission network supporting the country's air traffic control services. The problem caused flight delays and cancellations at several airports, including Rome and Milan.

Italy's air navigation service provider, ENAV, later announced that the technical issue had been resolved and that full air traffic management capacity had been restored.

What Caused the Flight Disruptions?

ENAV detected anomalies in its nationwide data transmission network overnight. The network supports air traffic control services across Italy.

As the volume of air traffic increased on Friday morning and the technical issue persisted, temporary traffic-management measures were introduced. These measures reduced the number of aircraft that could be handled within Italian airspace at one time.

ENAV said that alternative systems were activated to maintain air traffic control services while technicians worked to restore the primary network.

Rome and Milan Airports Among Those Affected

The disruption affected flights at major Italian airports, including:

• Rome Fiumicino Airport (FCO)
• Milan Malpensa Airport (MXP)
• Other airports operating within Italy's airspace

Reuters reported that aviation analytics company Cirium counted 192 flight cancellations at around 10:00 GMT on October 16. At that time, approximately 31% of flights departing Italian airports had left on schedule. The on-time departure rate was lower at Milan Malpensa and Rome Fiumicino.

These figures describe the situation during the disruption and should not be interpreted as current airport performance.

Was the Incident a Cyberattack?

ENAV stated that malicious activity had been ruled out as a possible cause of the technical anomalies. The company identified the data transmission network as the source of the problem.

The incident was therefore reported as a technical network fault, not a confirmed cyberattack or act of sabotage.

Air Traffic Capacity Restored

Later on October 16, ENAV announced that the problems affecting the primary data transmission network had been resolved. The company confirmed that operational capacity had returned to 100% and that the temporary restrictions had been lifted.

Although the air traffic control system returned to full capacity, passengers whose flights were delayed or cancelled could still be affected by changes to airline schedules and aircraft rotations.

What Should Passengers Do?

Passengers travelling through Italian airports should check their flight status directly with their airline, particularly if they were scheduled to travel during the disruption on October 16.

• Check the latest departure time before leaving for the airport.
• Review airline emails and text messages for schedule changes.
• Contact the airline if a flight was cancelled or a connection was missed.
• Keep booking confirmations and receipts for any additional expenses.
