Claude has become the AI assistant of choice for developers, writers, and analysts who need nuanced, long-context responses. When Claude suddenly becomes unavailable, workflows grind to a halt. The first question is always: is Claude down for everyone, or is it just me?
How to Check if Claude is Down (5 Methods)
Before troubleshooting your own connection, confirm whether Anthropic is experiencing a platform-wide outage:
1. Anthropic's Official Status Page
Visit status.anthropic.com for real-time status across Claude.ai, the Claude API, and Anthropic's infrastructure. This is the authoritative source — Anthropic posts incident updates here within minutes of identifying issues.
2. DownDetector for Crowdsourced Reports
DownDetector aggregates user-submitted reports and often shows spikes before Anthropic's official acknowledgment. A surge of 200+ reports is a strong signal of a real outage.
3. Search X/Twitter for Real-Time Reports
Search "Claude down" or "Anthropic down" on X. Developers are quick to post when Claude API calls start failing — you'll usually see reports within 5 minutes of a major outage.
4. Test the Claude API Directly
If you use the Claude API, send a simple test request. An HTTP 529 ("overloaded") or 503 response confirms server-side issues. This helps distinguish API outages (which affect your integrations) from web UI issues (which only affect claude.ai).

Sometimes connectivity issues are local. Try claude.ai from mobile data if your Wi-Fi is the problem. If it works on mobile, the issue is network-side, not Anthropic.
Why Does Claude Go Down? Common Causes
- Model Deployment Spikes: Anthropic releases new Claude versions frequently. Deployments can cause temporary instability as traffic is migrated.
- Demand Spikes: Claude usage surges after viral moments — a new model release or a major tech news cycle can overwhelm capacity within hours.
- AWS Infrastructure: Anthropic runs primarily on AWS. AWS us-east-1 or us-west-2 issues can directly impact Claude.
- Rate Limiting at Scale: API rate limits exist per-account and globally. During high load, requests may be throttled before full outages are declared.
- Safety System Maintenance: Anthropic's Constitutional AI systems require periodic updates, which can cause brief service interruptions.
Action Plan: What to Do When Claude is Down
For Individuals & Teams:
- Verify it's platform-wide by checking status.anthropic.com.
- Switch to ChatGPT, Gemini, or Perplexity for time-sensitive tasks.
- Claude Pro subscribers get priority during capacity events — consider upgrading.
- Follow @AnthropicAI on X for real-time incident updates.
For Developers Using the Claude API:
- Implement exponential backoff: start at 1s, double each retry, cap at 60s.
- Set up a fallback to OpenAI or Google Gemini for mission-critical paths.
- Monitor your API error rate dashboard — distinguish 429 (rate limit) from 529 (overloaded).
- Use Alert Pro for sub-60-second notifications when Anthropic's API degrades.

Many users conflate claude.ai (the web interface) with the Claude API. They're separate systems that can fail independently:
claude.ai (Web Interface)
- • Powers the chat interface at claude.ai
- • Uses its own authentication layer
- • Outages here affect chat users
- • Status shown on status.anthropic.com under "Claude.ai"
Claude API (api.anthropic.com)
- • Powers developer integrations
- • Used by Claude Code, Cursor, and thousands of apps
- • Outages here break production applications
- • Has separate status on status.anthropic.com
Frequently Asked Questions
Is Claude down for everyone or just me?
Check status.anthropic.com. If the page shows an active incident, it's platform-wide. If status is green but Claude isn't working, try a different browser, clear cookies, or test on mobile data.
How long do Claude outages typically last?
Minor capacity issues resolve in 10-30 minutes. More significant infrastructure issues can take 1-4 hours. Major incidents are rare but may last longer. Anthropic posts regular updates during active incidents.
Does Claude Pro have better uptime than the free tier?
Claude Pro users get priority access during high-demand events, which effectively means better availability when free users are being rate-limited. During true infrastructure outages, all tiers are affected equally.
How do I monitor the Claude API for my application?
Use Better Stack to create a monitor for api.anthropic.com with a test prompt. Set alert thresholds for latency and error rates. Alert Pro from APIStatusCheck also monitors Anthropic status and alerts you via email.
