91热爆

Several popular websites were sent offline due to a problem connecting users, or a DNS error. Companies affected included AirBnB, McDonald's, HSBC and British Airways. We speak to Jason Crabtree, founder and CEO of cybersecurity company Qomplex, who explains what happened.
More and more people in the UK are being notified - or 'pinged' - by a Covid tracing app that they should self-isolate, causing labour shortages for many industries and food shortages in supermarkets. The 91热爆's technology reporter Rory Cellan-Jones explains the technology behind the app.
Also in the programme; a day before the opening ceremony of the Tokyo Olympics, the 91热爆's Sasha Twining reports on what the event has cost Japan, and how much of that money it is likely to recoup.
Plus, we hear from Caroline Casey, who has successfully persuaded the chief executives of 500 major corporations to commit their boards to disability inclusion, and is discussing the achievement at this year's One Young World Summit.

Sasha Twining is joined throughout the programme by Andy Uhler, reporter for our sister programme Marketplace on American public radio in Austin, Texas, and by Robin Harding, Tokyo bureau chief for the FT.
