The number of people attempting to track the plane on Tuesday caused the website to run into problems, but not before more than half a million were able to briefly follow.
“In the moments before take-off, nearly six million people attempted to follow the flight, causing disruption to our platform,” a statement on Flightradar24’s Twitter account read.

A later tweet confirmed: “600k able to follow. Six million total attempts (which is what brought the site down).”
Flight KRF01R was the most-tracked flight in the world on Flightradar24 once the website recovered, with more than 350,000 watching the Boeing C-17A Globemaster III as it moved south through the UK, having left Edinburgh at 7.42pm on Tuesday. The plane landed shortly before 7pm in north-west London.
