28 Feb 2022: Viasat Inc said it was investigating a suspected cyberattack that caused a partial outage in its residential broadband services in Ukraine and other European countries.

– The outage was across Viasat’s KA-SAT network, which provides high-speed satellite internet coverage in Europe and Mediterranean markets.

– The outage could have been due to a distributed denial of service (DDoS) attack, Sky News reported on Monday. Such attacks hit a number of Ukrainian banks and government websites shortly before Russia’s invasion last week.

German internet service provider EUSANET is also reporting outages that began around the same time as both the Viasat outages and the Russian invasion.

– Golem, a German IT news site, reported Sunday that Viasat emailed partners with confirmation that broadband services across Europe were offline, starting Feb. 24 with Ukrainian spot beams.

– It is unclear how many customers Viasat has in Ukraine, and the company declined to say how many are being affected.

– An additional look on 4 March revealed service has been restored.

– Viasat operates large satellites in geosynchronous orbit – meaning they are stationary at a point about 35,000 kilometers from Earth to maximize coverage area.

– Currently Viasat operates a constellation of 4 GEO satellites (Anik F2 <2004>, Wildblue 1<2006>, Viasat 1<2011> and Viasat 2<2017>. A 5th, Viasat 3 is scheduled to launch summer ’22.
