SpaceX CEO Elon Musk said that his company’s Starlink satellite broadband service has been activated in Ukraine amid a crisis following Russia’s invasion.

Ukraine’s Vice Prime Minister Mykhailo Fedorov had pleaded with Musk to provide satellite-based communications to help resist the invasion. Responding to Fedorov, Musk tweeted, “Starlink service is now active in Ukraine,” adding that “more terminals are en route.”

Earlier in a tweet addressed to the billionaire, Fedorov had said, “While you try to colonize Mars — Russia try to occupy Ukraine! While your rockets successfully land from space — Russian rockets attack Ukrainian civil people! We ask you to provide Ukraine with Starlink stations.” He called on Musk “to address sane Russians to stand” against their government’s invasion.

Fedorov later thanked Elon Musk and Ukraine’s ambassador to USA Oksana Markarova for swift decisions that allowed Ukraine to activate the Starlink service.

Ukraine has seen a “series of significant disruptions of internet service” since Russia launched military operations in the country on Thursday.

Starlink operates a constellation of over 2,000 satellites that ease internet access across the planet. The activation of Starlink services would circumvent Russia’s attempts to cut off Ukraine’s internet from the world.
