On February 4, pro-war military bloggers reported that Russia’s frontline troops had lost access to Starlink satellite Internet. While Ukrainian forces have had official access to Starlink since the start of the full-scale invasion, many Russian units have relied on contraband devices as a key element of their battlefield communications. Until now, Elon Musk’s SpaceX has appeared willing to turn a blind eye to Russia’s unauthorized use of Starlink. Previous system failures that were mistaken for targeted outages turned out to be false alarms, and Ukrainian officials warned that cutting off Starlink access in Russian-occupied territories would be “catastrophic” for Kyiv’s frontline drone warfare. This time, however, the outage is not accidental: it comes after Russian troops started equipping their own drones with Starlink en masse and carrying out attacks on the Ukrainian army’s rear positions. Now, Kyiv and SpaceX face the challenge of engineering a Starlink blackout for the Russian side without hampering the Ukrainian military.
