According to data from Downdetector, there was a notable surge in complaints, indicating that a wide range of users were affected. Reports escalated from a baseline of one to over 230 around 12:41 PM. The outage graph revealed smaller spikes earlier in the day, culminating in a more significant increase around midday.
Claude serves as Anthropic’s AI assistant platform, facilitating consumer chat services, developer tools, and enterprise applications through its models like Opus, Sonnet, and Haiku.
Impact on Claude Chat
Data from Downdetector indicated that the majority of complaints were associated with Claude Chat. Approximately 62% of the reports were linked to this service, while 17% pertained to the app and 15% to the website.
Users also reported difficulties with logging in, accessing the API, and experienced latency issues. Social media posts revealed that some users could not load conversations, obtain responses from Claude, or access related services.
The outage seemed to impact both web and app users, suggesting a systemic platform issue rather than problems specific to certain devices.
