Hello and welcome to Newsar from the BBC World Service

comedy live from our studios in Central London.

I'm Julian Marshall. Now it's hard to escape the irony of a firm dedicated to

protecting other companies and institutions from cyber attacks itself creating massive computer disruption around the world.

But that's what happened today.

airports, banks, media outlets and hospitals were among those to suffer problems.

Crowdstake is aware of reports of crashes.

Computer security company Crowdstrike has been linked to the outage that is affecting banks, airports, supermarkets and businesses

Well I'm in the heart of Tokyo I am in Shibuya and the Budget Airline Jet Star Japan has been experiencing

disruptions it's had to cancel dozens of its domestic flights families here

are also getting ready for the summer holidays.

Was it about 3 o'clock when suddenly all of our computer screens flashed blue, the dreaded

so-called screen of death, and the media really does depend, particularly television.
