Senators order Musk to preserve SpaceX records over Ukraine Starlink access

The demand follows a period in October during which Ukrainian forces reported interruptions to Starlink service, and a statement on 12 November by President Volodymyr Zelenskyy that a limit on terminal movement speed had returned. SpaceX has denied that any change has been made to the service. The letter is a preservation and information request, not a finding of wrongdoing, and it does not establish that any restriction was ordered by Musk or by SpaceX.

The letter and its requirements

According to the Senate Foreign Relations Committee, the letter instructs Musk and SpaceX to preserve all records concerning Ukraine's access to Starlink and Starshield, including communications with the White House and the Pentagon. The preservation requirement extends to records held on personal devices and on encrypted messaging applications, and it covers the period from 1 September 2026 onwards. The senators have asked for written confirmation that the records have been preserved, together with answers to their questions, by 30 November 2026.

The scope of the request is broad. Starlink is the commercial satellite internet service operated by SpaceX, and Starshield is the related service developed for government and defence use. Both systems are used by Ukrainian forces for communications on the front line, and the senators' letter treats access to both as a matter of congressional oversight.

The preservation demand is procedural in character. A preservation letter of this kind requires the recipient to retain material that may be relevant to a future inquiry, and it does not, by itself, constitute a conclusion that the recipient has acted improperly. The letter asks SpaceX to account for the events of October and November, and the answers it receives will determine what further action, if any, the committee takes.

The October disruption

The letter refers to a disruption of Starlink service for Ukrainian forces between 13 and 24 October 2026. During that period, Ukrainian units reported that connectivity was degraded, and the senators' letter states that approximately 4,000 Russian aerial attacks took place in the same period. The figure of approximately 4,000 attacks is the figure given in the letter; it has not been independently verified by the sources consulted for this article.

Service was restored on 24 October 2026, according to the account set out in the letter. The cause of the disruption remains contested. Accounts of the episode differ on who ordered the October restrictions and on what mechanism produced them, and no single account has been confirmed by all of the parties involved. The senators' letter seeks the underlying records in order to establish the sequence of decisions, and the company has not publicly disclosed the internal communications that would resolve the question.

The October disruption is the central event behind the preservation demand.

The reported November limit

On 12 November 2026, President Zelenskyy reported that a limit on terminal movement speed had returned, describing a restriction of 161 kilometres per hour (100 miles per hour) on the speed at which a Starlink terminal can move while remaining connected. According to Zelenskyy, the limit hampers the operation of interceptor drones, which rely on Starlink connectivity while in motion. The limit is a restriction on the movement speed of the terminal, not a cap on internet download or upload speed, and it should not be described as one.

SpaceX has denied that any change has been made. In a public statement, the company said: "This is false. There has been no change." The denial and the Ukrainian report therefore stand in direct conflict, and the available public reporting does not resolve which account is correct.

A further nuance concerns the geographic scope of the reported limit. Zelenskyy described the restriction as applying across the entire front line and occupied territory. Sources in the Ukrainian Defence Ministry, however, have said that the limit was recorded across Russian-occupied territory only, and that no such limit was detected in Kyiv-controlled areas. The discrepancy between the two accounts has not been reconciled in the public reporting, and it remains an open question whether the restriction, if it exists, applies uniformly or only in particular areas.

Why it matters

The dispute matters for three reasons. First, Starlink is a central element of Ukrainian military communications, and any interruption or restriction affects the ability of front-line units to coordinate. The October disruption coincided with a period of intense Russian aerial activity, and the senators' letter draws an explicit connection between the timing of the disruption and the scale of the attacks. The restoration of service on 24 October ended the episode, but the recurrence reported in November has renewed the concern.

Second, the episode raises a question of governance over a privately operated system that has become part of a war effort. Starlink is owned and operated by a private company, yet it carries communications on which a state at war depends. The senators' letter is an attempt to establish, through the preservation of records, who decided what happened in October and whether any external instruction was involved. The answer to that question will shape the debate over the terms on which private satellite services are used in conflict.

Third, the conflicting accounts of the November limit illustrate the difficulty of verifying technical claims about a system whose operator and whose users disagree. SpaceX states that nothing has changed, while the Ukrainian president states that a limit has returned. The Defence Ministry sources add a third position, in which a limit exists but only in occupied territory. Until the records are produced or further technical evidence is published, the question cannot be settled from public statements alone.

What happens next

SpaceX has until 30 November 2026 to confirm that the records have been preserved and to answer the senators' questions. The committee will then decide whether the material it receives warrants further inquiry. No hearing has been announced, and no further action has been taken at the time of writing.

The technical question of the reported speed limit may be resolved sooner if SpaceX provides further detail or if Ukrainian technical sources publish measurements that establish where, if anywhere, the limit applies. Until then, the public record consists of a presidential report, a corporate denial, and a preservation demand from two senators.
