One of the world’s largest commercial satellite operators is probing a suspected cyberattack which has disrupted residential broadband services in eastern European countries including Ukraine.
Sky News understands that Viasat has appointed cybersecurity experts to investigate the causes of a service outage across its KA-SAT network in recent days.
Industry sources said potential Russian involvement in the incident was being explored, though there was no concrete evidence of this so far.

In a statement, Viasat said it was “experiencing a partial network outage-impacting internet service for fixed broadband customers in Ukraine and elsewhere on our European KA-SAT network”.

“We are investigating and analysing our European network and systems to identify the root cause and are taking additional network precautions to prevent further impacts while we attempt to recover service to affected customers.

Western companies are on high alert for Russian state-sponsored cyberattacks, with Lloyds Banking Group’s chief executive last week among those acknowledging intensified corporate preparations for such incidents.
