Webhook receives a JSON payload on every status transition. Fire-and-forget — no auth from us; the URL is its own secret.
Methodology
- Probe
- We send a GET request to the target URL from each region and time the full response.
- Counts as DOWN
- Every region fails the request (connect refused, DNS error, timeout, or HTTP 5xx).
- Counts as DEGRADED
- At least one region succeeds but at least one fails — the outage is partial or regional.
- Detail
- Per-region results include HTTP status code, response time, and best-effort DNS / connect / TLS / first-byte phase timings when the Node HTTP client exposes them.
- Cadence
- Every 5 minutes, in parallel across 4 monitoring regions (US East Virginia, US West Oregon, Europe London, Asia Singapore).
- Rate-limited targets
- If a host returns 429 or consistently drops connections from our IPs, we cap retries at 3 and report the last observed status — we do not flood the target to confirm the outage.
- Data source
- Direct probes from our monitoring infrastructure. We do not aggregate crowd reports, Twitter mentions, or DownDetector signals — every result on this page is a live network request.
Common questions
Why is Anthropic API down right now?
Anthropic API outages are usually caused by server overloads, failed deployments, CDN or DNS problems, DDoS attacks, or regional internet routing issues. isitdown.io checks Anthropic API from 4 regions (US East, US West, Europe, Asia) simultaneously. If all 4 fail, Anthropic API is down for everyone. If only some fail, the outage may be regional. If all pass but you still can't connect, the issue is on your local network, VPN, or DNS.
How can I check if Anthropic API is down for everyone or just me?
Click "Check Anthropic API now" above. isitdown.io pings api.anthropic.com from four global regions in parallel and reports which ones succeeded. If all four pass, the issue is local — try flushing your DNS cache, switching networks, disabling your VPN, or using a different browser. If two or more regions fail, the outage is on Anthropic API's side.
