Italy ATC Network Failure: Mass Flight Disruptions Strike Rome and Milan
A data network failure knocked Italy's air traffic control system to half capacity on 16 October 2026, causing nearly 200 cancellations.

Italy's air traffic control system suffered a serious data network failure on Friday 16 October 2026, cutting capacity to around half its normal level and triggering widespread flight cancellations and delays at airports across the country, including Rome Fiumicino (FCO) and Milan Malpensa (MXP).
The disruption centred on the data transmission network that carries information between systems supporting Italy's nationwide air traffic control services. Air navigation service provider ENAV said backup systems initially allowed controllers to maintain normal operations, but as morning traffic built and the fault persisted, capacity restrictions were introduced at 06:00 local time.
What the Italy ATC Failure Looked Like in Numbers
By noon local time, AeroTime reports that aviation analytics company Cirium had counted 192 flight cancellations across Italy. Only around 31% of departures had left on time nationally.
The situation was worse at the country's two busiest hubs. At Milan Malpensa, just 25% of departures were on time, while Rome Fiumicino fared only slightly better at 28%. Passengers at airports serving Rome, Milan and Bergamo were among those most affected.
Euronews reported that delays and cancellations disrupted Rome Fiumicino in particular throughout Friday as the fault took hold.
How ENAV Managed the Crisis
With the primary data network down, controllers relied on a secondary satellite network while technicians worked to restore the main connection. That backup kept air traffic control services running but could not support the full volume of flights, which is why ENAV imposed restrictions rather than suspending operations entirely.
Capacity was later raised to 75% as work progressed, before ENAV confirmed that the primary network had been fully restored and normal capacity reinstated, according to AeroTime.
What Caused the Network Fault
ENAV was clear that its air traffic control equipment was functioning normally throughout the episode. The problem was identified as a fault in the network carrying data between systems, not in the control systems themselves.
The provider said it worked with outside suppliers to investigate and resolve the issue. One of those suppliers was telecommunications company TIM, which manages and maintains the data network, according to AeroTime.
ENAV also ruled out malicious activity as a cause of the failure.
Advice to Passengers
Rome airport operator ADR and Milan airport operator SEA both advised travellers to check with their airlines directly for the latest information on individual flights, AeroTime notes.
Flight schedules began returning to normal once ENAV confirmed full capacity had been restored, though recovery from a disruption of this scale typically takes time to work through the system as airlines reposition aircraft and crew.

The Bottom Line
A single network fault in Italy's data transmission infrastructure was enough to halve the country's air traffic capacity during one of the busiest parts of the operating day. The episode underlines how dependent modern air traffic management is on reliable data connectivity, even when the control equipment itself remains fully operational.
ENAV's use of a secondary satellite network prevented a total shutdown, but the backup could not absorb anything close to normal traffic volumes. The result was nearly 200 cancellations and on-time performance that collapsed to below one in three departures nationwide.
