About Anthropic & Technical Insights
What this service does and the technologies behind it.
Read the tech stack as text▾
Overview: A content-heavy AI brand using a headless CMS, object storage, edge CDN, and analytics to deliver a fast, globally accessible site.
What stands out

- Cloudflare plus Amazon S3 suggests a global performance focus, key for an AI company with international users.
- Google Tag Manager and Analytics reveal a data-driven marketing approach to optimize visitor acquisition and conversion.
- The presence of jQuery amid a modern stack points to legacy code or third-party scripts still in use.

- Sanity runs on Sanity.io — Sanity CMS runs on the hosted Sanity.io platform, which provides its editing studio, real-time APIs, and content lake.
- Google Analytics integrates with Google Tag Manager — Tag Manager loads Google Analytics scripts, allowing marketing to track user journeys without code changes.
- Cloudflare requires HTTP/3 — Cloudflare terminates HTTP/3 connections, enabling faster and more reliable page loads over modern networks.

How to fix Anthropic not working
Anthropic makes Claude, an AI assistant, and the Anthropic API that developers use to build with it. Claude is also available through Claude Code and through major cloud platforms. Most problems come from a sign-in, a usage limit, a request the API refused, or the service itself. Use the status page first, since it shows whether there is a known incident.
Jump to what you are seeing
Website
The Anthropic website or the Claude sign-in page does not load for you.
- Open the page in a private window and on another network.
- Check status.anthropic.com for an active incident.
- If other sites load but this one does not, ask your IT team to check the address is not blocked by a filter.
Claude
The Claude app or chat does not respond, or a conversation does not load.
- Reload the page, or close and reopen the app. Start a new conversation to see whether the problem is one chat.
- Check status.anthropic.com for an incident affecting Claude.
- Try another browser or device. If it works there, clear the site data for the app on the device where it fails.
- If Claude stays unavailable for you only, contact support through the help option with the time and the device.
API
Calls to the Anthropic API fail or return an error.
- Check the status code. A 401 means the API key is missing or wrong. A 403 means the key does not have permission for the request. A 429 means you have hit a rate or usage limit, so wait and retry with a growing delay.
- A 5xx means a problem on the service side. Check status.anthropic.com before changing your code.
- Confirm the key has not been revoked, and that it is set in the environment your code reads.
- Keep the request ID from the response and the time, so support can trace the call.
Still not working?
If it still does not work, contact Anthropic support through the help option in the Claude app, on the Anthropic website, or in the API console. Have your account or organization name, the exact error message and status code, the time it started with your time zone, and any request ID shown. Never send your API key in a support message. Live incident updates are on status.anthropic.com.
Most problems on an AI service clear with a reload or a short wait, and a rate limit usually resets on its own. This status page shows live incidents, so you can see whether the service is affected.
