Ukrainian developer Yar Birzul, founder of the company ARCHON, reported that Meta has effectively blocked access from Ukrainian IP addresses to its new programming AI agent Muse Code and the flagship Muse Spark 1.3 models. According to him, the tool cannot currently be used directly from a Ukrainian IP address in the command line, whereas after connecting through a VPN with servers in the US, Europe, or Asia, the system works without any issues. As a result, in practice the service is available to Ukrainian specialists only via VPN or third-party intermediaries.
How the block manifests
According to the developer's account, when attempting to use Muse Code from a Ukrainian address, the system constantly demands re-authentication, which cannot be completed through Meta's official developer portal. This makes launching the agent directly from the command line impossible. At the same time, switching to a foreign IP address via VPN fully resolves the problem: the tool starts up and works normally. The difference in the system's behavior on Ukrainian versus foreign IPs, in Birzul's assessment, points to a geoblock at the level of Meta's infrastructure, rather than an authentication failure.
Meta's official policy
Under Meta's official rules (Geographic Use Policy), restrictions on using its services are supposed to apply only to temporarily occupied territories — Crimea, Donbas, and Luhansk region. According to the company's statement, it is these regions that fall under the geographic restrictions. However, in practice, as the Ukrainian developer claims, the sanctions filters may have been extended to the entire territory of Ukraine, which goes beyond the officially declared policy and affects the Kyiv-controlled regions.
Contradictory data
There is a direct discrepancy here between the stated policy and the observed behavior of the system. On the one hand, Meta's Geographic Use Policy limits the block to temporarily occupied territories. On the other hand, the user's actual experience shows that access is closed for Ukrainian IPs in general, not just for occupied zones. An additional inconsistency concerns the model versions: recent materials mention Muse Spark 1.3, whereas the company's earlier reviews described the release of Muse Spark 1.1. This may reflect a phased update of the product line, but the exact chronology of versions cannot be confirmed without a comment from Meta itself.
Developer's reaction and the company's position
After the Ukrainian developer sent Meta a series of requests asking it to clarify the reasons for the geoblock and restore access in the Ukraine-controlled territories, his account was, according to him, blocked. As of the time of publication, no official responses or public comments from Meta representatives had been received. Thus, the incident remains documented from the side of a single user and Ukrainian media, while the tech giant's position on the scale of the restrictions and the account block has not been publicly commented on.
