The festival itself really doesn’t appeal, but the infrastructure required is incredible.

How Glastonbury Festival builds a city-sized phone network for just one weekend
In 2010, data usage over the Glastonbury network reached 0.11 terabytes. In 2013, the first year of 4G at the festival, it jumped to 12.3, and at the last event in 2017 (2018 was a fallow year) it rose to 54.2 terabytes. The busiest time for data uploads was during the “legends” slot on Sunday afternoon, when Bee Gee Barry Gibb took to the Pyramid Stage. This year, EE predicts that data usage will pass 60 terabytes – with 5G being brought to the festival for the first time to take on some of the load.

The main challenge is not coverage but capacity, given the tight geographic space people are packed into. “We’re looking at Glastonbury being the size of York, but the capacity required is more like central London,” says Bennett.
