SEV1: Complete Outage

Symptoms:

• 100% transcription failure
• API returning 5xx errors
• Complete service unavailability

Immediate Actions:

1. Acknowledge incident in PagerDuty/Slack
2. Check Deepgram status page
3. Verify API key is valid
4. Check network connectivity
5. Activate fallback if available

// Fallback activation
import { FallbackManager } from './fallback';

const fallback = new FallbackManager();

// Activate fallback mode
await fallback.activate({
  reason: 'SEV1: Deepgram API outage',
  mode: 'queue', // Queue requests for later
  notifyUsers: true,
});

// Or switch to backup provider
await fallback.switchProvider('backup-stt-provider');

Communication Template:

## Incident: Deepgram Service Outage

**Status:** Investigating
**Severity:** SEV1
**Started:** [TIME]
**Impact:** All transcription services unavailable

### Summary
We are experiencing a complete outage of our transcription service due to
Deepgram API unavailability.

### Current Actions
- [ ] Verified Deepgram status page shows incident
- [ ] Contacted Deepgram support
- [ ] Activated fallback queueing
- [ ] Notified affected customers

### Next Update
In 15 minutes or when status changes.

SEV2: Major Degradation

Symptoms:

• 50%+ error rate
• Intermittent failures
• Significantly elevated latency

Investigation Steps:

// scripts/investigate-degradation.ts
import { createClient } from '@deepgram/sdk';
import { logger } from './logger';

async function investigateDegradation() {
  const client = createClient(process.env.DEEPGRAM_API_KEY!);
  const testUrls = [
    'https://static.deepgram.com/examples/nasa-podcast.wav',
    'https://your-test-audio.com/sample1.wav',
    'https://your-test-audio.com/sample2.wav',
  ];

  console.log('Testing transcription across multiple samples...\n');

  const results = await Promise.allSettled(
    testUrls.map(async (url) => {
      const startTime = Date.now();
      const { result, error } = await client.listen.prerecorded.transcribeUrl(
        { url },
        { model: 'nova-2' }
      );

      return {
        url,
        success: !error,
        latency: Date.now() - startTime,
        error: error?.message,
        requestId: result?.metadata?.request_id,
      };
    })
  );

  // Analyze results
  const successful = results.filter(r => r.status === 'fulfilled' && r.value.success);
  const failed = results.filter(r => r.status === 'rejected' || !r.value?.success);

  console.log(`Success: ${successful.length}/${results.length}`);
  console.log(`Failed: ${failed.length}/${results.length}`);

  if (failed.length > 0) {
    console.log('\nFailed requests:');
    failed.forEach(f => {
      if (f.status === 'fulfilled') {
        console.log(`  - ${f.value.url}: ${f.value.error}`);
      } else {
        console.log(`  - Exception: ${f.reason}`);
      }
    });
  }

  // Check if it's a specific model or feature
  console.log('\nTesting different models...');
  for (const model of ['nova-2', 'nova', 'base']) {
    const { error } = await client.listen.prerecorded.transcribeUrl(
      { url: testUrls[0] },
      { model }
    );
    console.log(`  ${model}: ${error ? 'FAIL' : 'OK'}`);
  }
}

investigateDegradation().catch(console.error);

Mitigation Options:

1. Reduce request rate
2. Disable non-critical features
3. Switch to simpler model
4. Enable request retries

SEV3: Minor Degradation

Symptoms:

• Elevated latency (2-3x normal)
• Occasional timeouts
• Reduced throughput

Actions:

// Enable graceful degradation
const gracefulConfig = {
  // Increase timeouts
  timeout: 60000, // 60s instead of 30s

  // Enable aggressive retry
  retryConfig: {
    maxRetries: 5,
    baseDelay: 2000,
    maxDelay: 30000,
  },

  // Use simpler model for faster processing
  model: 'nova', // Instead of nova-2

  // Disable expensive features
  features: {
    diarization: false,
    smartFormat: true, // Keep basic formatting
  },
};

Post-Incident Review

## Post-Incident Review: [INCIDENT-ID]

### Timeline
- **HH:MM** - First alert triggered
- **HH:MM** - Incident acknowledged

Diagnostic Commands

Check Current Status

# API connectivity
curl -s -w "\nStatus: %{http_code}\nTime: %{time_total}s\n" \
  -X GET 'https://api.deepgram.com/v1/projects' \
  -H "Authorization: Token $DEEPGRAM_API_KEY"

# Test transcription
curl -X POST 'https://api.deepgram.com/v1/listen?model=nova-2' \
  -H "Authorization: Token $DEEPGRAM_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://static.deepgram.com/examples/nasa-podcast.wav"}'

Check Application Metrics
