ENAV data network failure cuts Italian air traffic handling to about 50%

Italy’s air traffic control capacity was reduced to roughly 50% in the morning after a data network failure at ENAV, the state‑run air navigation service provider.

Four flights to Milan Linate, Riyadh, Tirana and Trieste were cancelled and around twenty departures were delayed between 15 and 60 minutes, while Lamezia Terme experienced delays of three to four hours; the disruption affected airports including Rome Fiumicino, Milan Linate, Milan Malpensa, Bergamo Orio al Serio and Lamezia Terme. ENAV said the issue was confined to the data network managed by TIM and ruled out any malicious activity, noting a similar failure on 28 June 2025 that had impacted 320 flights.
