The real problems start when schools get suspended. Usage of Italy’s national network has surged by more than two-thirds, not due to working from home, but due to housebound schoolchildren logging on to games such as Fortnite, according to a report from Bloomberg News.

Spikes in usage are most likely to affect people who pay for their internet with bandwidth caps, particularly common in the US and among those who rely on mobile broadband. Some American ISPs, including AT&T, have started suspending the practice in order to avoid being blamed for preventing work, but not everyone has done so.
