chatbot is not working and Anthropic says it is investigating an issue

This afternoon may not be the best time to leave any task in the hands of Anthropic’s AI. Most of the services of the company led by Dario Amodei are giving global failures this Tuesday. Everything points to a general decline, with two clear exceptions: Claude for Government and Claude Console, the management platform aimed at developers and companies.

The details are visible on the Anthropic status page. claude.aithe gateway to the chatbot both in its web version and in the desktop and mobile apps, is completely out of service. We have been able to verify it: when trying to use it, the macOS application displays a clear message, “You cannot connect to Claude,” and invites you to check the Internet connection.

They are also registering API problemsthe path that allows professional clients, such as developers and companies, to integrate Anthropic services into their own applications. This is the case of those who use it to power customer service chatbots or to access models such as Sonnet 4.6 and Opus 4.7 in Perplexity. On this front, the drop is partial: everything points to higher error rates or intermittent failures for some users.

Claude Code It is also not spared and is experiencing a partial decline. The impact can be significant: it is one of the most established agentic AI tools on the market. Its adoption in developer workflows is increasing, so any failure can have direct consequences on the productivity of many people.

For now It is not clear what caused the incidentalthough we do know that Anthropic teams are working to resolve it. The company itself has been updating the situation on its status page, which allows us to reconstruct a brief chronology of the events.

• April 28, 2026, 17:41 UTC (19:41 Spanish peninsular time). Anthropic detects the problem and begins the investigation.
• April 28, 2026, 17:51 UTC (19:51 Spanish peninsular time). Confirms bugs in the API, claude.ai and the login system.
• April 28, 2026, 18:33 UTC (20:33 Spanish peninsular time). It indicates that it is continuing to work to resolve the incident.

For now, we just have to wait for the incident to be resolved. Claude chatbot users can use alternatives as ChatGPT, Gemini or Grok. The problem is evident: when the Anthropic service does not work, access is lost to key elements such as conversation history, projects and other associated data. We will update this article as soon as there is news.
