Governments 'don't want to talk about' crises, says cyber security expert

Elisabeth Braw, cyber security threat expect at the Atlantic Council, told LBC News: “It’s just too unpleasant to think about - so governments prefer not to mention it, hoping there won’t be cyber incidents.

“Because we are unprepared, we are completely left to our own devices.”

IT outage ‘not a hack,’ says CrowdStrike boss

The President of CrowdStrike has said that today’s worldwide IT outage was not a ‘security or cyber incident’.

“Our customers remain fully protected,” he said.

“We understand the gravity of the situation and are deeply sorry for the inconvenience and disruption. We are working with all impacted customers to ensure that systems are back up and they can deliver the services their customers are counting on."

IT outage could take 'days' to fix

Experts have warned it could take “days” for the world to recover from today’s global IT outage.

Impacted systems will need to be started in ‘Safe Mode’, to remove the faulty update - and this could take big organisations several days to complete at scale

Increased demand on 999 and NHS 111 services

London Ambulance Service said it had seen: "Huge increases in the number of calls to both our 999 and 111 services.

"By 2pm today, we had received more than 3,000 999 calls and 3,000 calls to our 111 services – this is a third higher than we would usually receive in a full 24 hour period."

South Central Ambulance Service said it was experiencing increased demand on its 999 and NHS 111 services due to the global IT issues. 

 In a post on X, it said: "As usual, our 999 team will be prioritising patients in a serious or life-threatening condition. 

 "Patients not requiring such an immediate response may have to wait longer than usual to be seen by our ambulance team. 

 "If you have an urgent, not emergency, medical need rather than call 999 please make use of other local services, such as urgent treatment centres which remain open across our region until late this evening. 

 "You can also use 111 online, or call 111, to get advice and help." 

Passengers sent home from airports

43 UK departures have been cancelled.

Ryanair told passengers: "If your flight has been cancelled, we kindly request that you leave the airport as the IT outage means we cannot currently assist passengers at the airport."

Edinburgh Airport said: "Anyone whose flight is cancelled is asked to please leave the airport and contact their airline directly."

UK air traffic control provider Nats said its systems are "operating normally".

Friday is the busiest day of the year so far for UK air travel with 3,214 departing flights as thousands of families embark on summer holidays at the end of the academic year for many schools.

Several US carriers grounded flights, including United, American Airlines and Delta.

Train service information website National Rail Enquiries warned passengers of "widespread IT issues across the entire network", although most train services ran as scheduled.

South Western Railway said all its ticket vending machines had stopped working due to IT issues.
