Hundreds of flights are grounded after a “connectivity issue” affects National Air Traffic Services (NATS), leaving thousands of passengers stranded. Reporting describes the disruption as occurring at NATS offices in Prestwick, Scotland, and as leading to widespread flight cancellations or delays.

The incident is described as the second major flights disruption in about two weeks, raising questions about system resilience and operational continuity. One outlet frames the situation as creating scrutiny around the UK’s air safety leadership, while emphasizing that the immediate cause is linked to communications or network connectivity at NATS rather than weather or security incidents.

Across coverage, the common themes are the scale of the disruption, passenger impact, and the attribution to a connectivity-related problem at NATS in Prestwick, with this event appearing to follow a similar earlier meltdown. Details about exact technical mechanisms, duration of the outage, and how quickly services recover are not provided in the supplied accounts.
