Mistral AI Incident Runbook

Overview

Rapid incident response procedures for Mistral AI-related outages.

Prerequisites

• Access to Mistral AI console
• kubectl access to production cluster (if applicable)
• Prometheus/Grafana access
• Communication channels (Slack, PagerDuty)

Severity Levels

Level	Definition	Response Time	Examples
P1	Complete outage	< 15 min	Mistral API unreachable, all requests failing
P2	Degraded service	< 1 hour	High latency, partial failures, rate limiting
P3	Minor impact	< 4 hours	Occasional errors, non-critical feature down
P4	No user impact	Next business day	Monitoring gaps, documentation issues

Quick Triage

#!/bin/bash
# mistral-triage.sh

echo "=== Mistral AI Quick Triage ==="
echo "Timestamp: $(date)"
echo ""

# 1. Check Mistral API health
echo "1. Checking Mistral API..."
HTTP_STATUS=$(curl -s -o /dev/null -w "%{http_code}" \
  -H "Authorization: Bearer ${MISTRAL_API_KEY}" \
  https://api.mistral.ai/v1/models)
echo "   API Status: $HTTP_STATUS"

# 2. Check our health endpoint
echo ""
echo "2. Checking our service health..."
curl -s https://api.yourapp.com/health | jq '.services.mistral' 2>/dev/null || echo "   Health check failed"

# 3. Check recent error rate
echo ""
echo "3. Recent errors (if Prometheus available)..."
curl -s "localhost:9090/api/v1/query?query=rate(mistral_errors_total[5m])" | jq '.data.result' 2>/dev/null || echo "   Prometheus not available"

# 4. Check recent logs
echo ""
echo "4. Recent error logs..."
kubectl logs -l app=mistral-service --since=5m 2>/dev/null | grep -i error | tail -10 || echo "   kubectl not available"

Decision Tree

Mistral API returning errors?
├─ YES: Check api.mistral.ai/v1/models with curl
│   ├─ 401 → API key issue (see Auth section)
│   ├─ 429 → Rate limited (see Rate Limit section)
│   ├─ 5xx → Mistral service issue (wait & monitor)
│   └─ Timeout → Network issue (check connectivity)
└─ NO: Our service returning errors?
    ├─ YES → Check our logs & config
    └─ NO → Likely resolved, continue monitoring

Immediate Actions by Error Type

401 Unauthorized - Authentication Failed

# 1. Verify API key is set
echo "API Key length: ${#MISTRAL_API_KEY}"
echo "API Key prefix: ${MISTRAL_API_KEY:0:10}..."

# 2. Test API key directly
curl -v -H "Authorization: Bearer ${MISTRAL_API_KEY}" \
  https://api.mistral.ai/v1/models

# 3. Check if key was rotated
# → Verify in Mistral console: console.mistral.ai

# 4. Update key if needed
kubectl create secret generic mistral-secrets \
  --from-literal=api-key="$NEW_API_KEY" \
  --dry-run=client -o yaml | kubectl apply -f -

# 5. Restart pods
kubectl rollout restart deployment/mistral-service

429 Rate Limited

# 1. Check current rate limit status
curl -v -H "Authorization: Bearer ${MISTRAL_API_KEY}" \
  https://api.mistral.ai/v1/models 2>&1 | grep -i "rate\|retry"

# 2. Enable request queuing (if supported)
kubectl set env deployment/mistral-service RATE_LIMIT_MODE=queue

# 3. Reduce request concurrency
kubectl set env deployment/mistral-service MAX_CONCURRENT_REQUESTS=5

# 4. Long-term: Contact Mistral for limit increase
# → console.mistral.ai or support@mistral.ai

500/503 Service Error

# 1. Check Mistral status (if available)
echo "Checking Mistral status..."

# 2. Enable graceful degradation
kubectl set env deployment/mistral-service MISTRAL_FALLBACK=true

# 3. Notify users
# → Update status page

# 4. Monitor for recovery
watch -n 30 'curl -s -o /dev/null -w "%{http_code}" -H "Authorization: Bearer ${MISTRAL_API_KEY}" https://api.mistral.ai/v1/models'

Timeout/Network Error

# 1. Test connectivity
curl -v --connect-timeout 5 https://api.mistral.ai/v1/models

# 2. Check DNS resolution
nslookup api.mistral.ai

# 3. Increase timeout
kubectl set env deployment/mistral-service MISTRAL_TIMEOUT=60000

# 4. Check egress rules
kubectl get networkpolicy

Error Handling

Issue	Cause	Solution
kubectl fails	Auth expired	Re-authenticate with cloud provider
Metrics unavailable	Prometheus down	Check backup metrics or logs
Secret rotation fails	Permission denied	Escalate to admin
Fallback not working	Not implemented	Use cached responses or error page

Examples

One-Line Health Check

curl -sf -H "Authorization: Bearer ${MISTRAL_API_KEY}" https://api.mistral.ai/v1/models | jq '.data[0].id' || echo "UNHEALTHY"

Quick Rollback

kubectl rollout undo deployment/mistral-service && \
kubectl rollout status deployment/mistral-service
