Anthropic blocked hundreds of Russian users' Claude accounts

Anthropic blocked hundreds of Russian Claude users' accounts without warning. Among those affected were both ordinary users and professionals—developers, designers, content creators using the service for work.

How it happened

The wave of blocks occurred unexpectedly and affected hundreds of accounts across Russia practically simultaneously. Users discovered their access closed upon login attempts, but received no notifications, explanations, or advance warnings. This sharply differs from the usual practice of account blocking on web services—typically at least some explanation is provided. Those affected began actively discussing the situation on social media and professional communities. Among them were people for whom Claude was the primary productivity tool.

Possible causes

Anthropic is an American company and automatically complies with American legislation, including sanctions regimes. The US has imposed numerous restrictions on providing American services to Russian residents. The mass nature of the blocks indicates this was not combating individual violations but a systemic decision:

• Possible application of American sanctions mechanisms
• Absence of warning—characteristic of compliance with government requirements
• Simultaneous blocking of numerous accounts points to an automated solution

However, no official statement from Anthropic regarding the reasons followed.

What it means

The situation demonstrates how geopolitical factors directly impact the availability of Western services. For Russian business, this reinforces the trend toward localization: Yandex.GPT, MegaMozg, and other local solutions become more reliable in terms of access stability. Claude lost its position as the unconditional choice for critical work processes.
