On 28 October around 20:00 (UTC +1), a radar control failure at Lisbon area control center (ACC) seriously disrupted air traffic as aircraft were not able to take-off or land. Around 23:00 the failure got solved but delays are expected on all flights coming from the North and some from the West.
In air traffic control, an area control center (ACC), also known as a center (or in some cases, en-route, as opposed to TRACON control), is a facility responsible for controlling aircraft en route in a particular volume of airspace (a Flight Information Region) at high altitudes between airport approaches and departures. In the US, such a center is referred to as an air route traffic control center (ARTCC). (wikipedia: Area control center)
