A suspected Kremlin cyber-attack on American satellite internet company Viasat began about an hour before Russia invaded Ukraine on 24 February.

It caused outages for several thousand Ukrainian customers - and affected windfarms and internet users in Central Europe.

Officials have long believed Russia was to blame but lacked the evidence to say so publicly.

Viasat provides high-speed satellite broadband to commercial and military customers.

The company has previously said "tens of thousands of terminals" were damaged beyond repair, in the cyber-attack, though its core network infrastructure and the satellite itself remained unscathed.
