What is Anthropic?
Anthropic is an AI safety company that develops and operates the Claude family of large language models. Developers and businesses access Claude via the Anthropic API to build applications ranging from chatbots and coding assistants to document analysis and automated workflows. Claude.ai is Anthropic's consumer-facing chat product, while the API serves as the backbone for thousands of third-party integrations and production systems.
Signs Anthropic is having problems
- API requests return HTTP 529 (overloaded) or 500 errors instead of model completions
- Requests to api.anthropic.com hang or time out without a response, especially for longer prompts
- Claude.ai chat interface shows errors on message send, fails to load conversation history, or gets stuck on a spinner
- Streaming responses (server-sent events) cut off mid-generation or the stream never opens
Find out when your own services go down
You can check Anthropic here — but a heartbeat monitor tells you the moment your API, website, or cron job stops responding, so you hear about your own downtime before your users do.
Frequently asked questions
How can I tell if Anthropic is down?
The authoritative source is the official status page at https://status.claude.com, which lists real-time incident reports and component health for the API, Claude.ai, and related services. If you see no active incident there but your requests are still failing, the problem is likely on your end or in an intermediate network path.
Where is the official Anthropic status page?
Anthropic publishes its official service status at https://status.claude.com. That page covers the Claude API, Claude.ai, and supporting infrastructure. You can subscribe to updates directly from that page to receive email notifications when incidents are opened or resolved.
What should I do if the Anthropic API is returning errors?
First check https://status.claude.com for any active incident. If none is listed, verify your API key is valid, check that you have not exceeded your rate limits or usage tier, and review the error code in the response body. Anthropic's error reference in their documentation distinguishes between rate-limit errors (429), server errors (500), and overload errors (529), each of which calls for a different response.
Can I get automatically alerted when my own services that depend on Anthropic go down?
You can set up a heartbeat monitor on CronJobPro for any job or service that calls the Anthropic API. If the job stops reporting in on schedule, CronJobPro will alert you immediately, which is often faster than noticing failures manually. This does not tell you whether Anthropic itself is at fault, but it tells you that something in your pipeline has broken.
