PAYBACK TIME

A ROUND 9PM ON MONDAY 23 NOVEMBER 2020, the IT manager for a school in central London received a text message from a colleague, saying the school's website was down. He tried logging on but couldn't. At first, he thought he had forgotten the password. After several attempts, he realised that he was locked out.

The IT manager, Matthew (he asked us not to use his last name), works in a neighbourhood where affluence hides pockets of poverty, and migrant families from Pakistan, India and eastern Europe pin their hopes for their children on a small, publicly funded school. It has about 150 students aged between five and 10, many of them on free school meals. On a shoestring budget, in a Victorian building that's showing its age, teachers track the students' progress by photographing them as they learn how to hold a pencil, draw a picture or write their name. The snapshots and other progress reports are uploaded to a server, a powerful computer that processes data and provides services for other devices used around the school.

Matthew, in his early 40s, has guarded this irreplaceable trove of data on every child's learning since 2016. Although the school can only afford to pay him a few thousand pounds a year as a contractor, he is devoted to its people and mission. When he found he couldn't access the website, he was desperate.

I hoped Finland would be a progressive dream.I've had to think again Mike Watson

Oulu is five hours north from Helsinki by train and a good deal colder and darker each winter than the Finnish capital. From November to March its 220,000 residents are lucky to see daylight for a couple of hours a day and temperatures can reach the minus 30s. However, this is not the reason I sense a darkening of the Finnish dream that brought me here six years ago.
