Anthropic Incident Runbook

Severity Classification

Severity	Condition	Response Time
P1	API returning 500/529 for all requests	Immediate
P2	Rate limiting (429) or high latency (>10s p99)	15 minutes
P3	Intermittent errors (<5% error rate)	1 hour
P4	Degraded quality (not errors)	Next business day

Immediate Triage (First 5 Minutes)

# 1. Check Anthropic status page
curl -s https://status.anthropic.com/api/v2/status.json | python3 -c \
  "import sys,json; d=json.load(sys.stdin); print(d['status']['indicator'], '-', d['status']['description'])"

# 2. Test API connectivity
curl -s -w "\nHTTP %{http_code} | Time: %{time_total}s\n" \
  https://api.anthropic.com/v1/messages \
  -H "x-api-key: $ANTHROPIC_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -H "content-type: application/json" \
  -d '{"model":"claude-haiku-4-20250514","max_tokens":8,"messages":[{"role":"user","content":"1"}]}'

# 3. Check rate limit headers
curl -s -D - https://api.anthropic.com/v1/messages \
  -H "x-api-key: $ANTHROPIC_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -H "content-type: application/json" \
  -d '{"model":"claude-haiku-4-20250514","max_tokens":8,"messages":[{"role":"user","content":"1"}]}' \
  2>/dev/null | grep -i "ratelimit\|retry-after\|request-id"

Decision Tree

API returning errors?
├── 401/403 → Key issue → Check ANTHROPIC_API_KEY is set and valid
├── 429 → Rate limited → Check headers, reduce traffic, wait for retry-after
├── 500 → Server error → Check status.anthropic.com, retry with backoff
├── 529 → Overloaded → Temporary, retry after 30-60s
└── Timeouts → Network or long generation → Increase timeout, check max_tokens
