A widespread outage has brought thousands of websites down including major online services. 

Playsation, British Airways, AirBnB, McDonald's and Sky Bet are just some of the websites affected with websites loading slowly or showing “DNS failure.”

Customers of bank such as HSBC, Halifax, Lloyds Bank, Barclays, TSB, Bank of Scotland and Tesco Bank say websites and personal banking apps are down. 

It's not yet clear what the cause but its been reported that the problem could be stemming from content delivery company Akamai Technologies.
