15. Create incident channel: #incident-YYYY-MM-DD-HHMM
16. Post initial status

Quick Status Check Commands

# Site availability
curl -w "%{http_code} %{time_total}s" -s -o /dev/null https://www.albrittonanalytics.com

# DNS resolution
nslookup www.albrittonanalytics.com

# SSL certificate check
openssl s_client -connect www.albrittonanalytics.com:443 -servername www.albrittonanalytics.com < /dev/null 2>/dev/null | openssl x509 -noout -dates

3. Netlify Rollback Procedures

3.1 Dashboard Rollback (Fastest - 2-5 minutes)

When to Use: Site issues after recent deployment, need immediate rollback

Prerequisites: - Netlify dashboard access - Deployment history available - Knowledge of last known good deployment

Process:

1. Access Netlify Dashboard
2. Go to https://app.netlify.com

3. Navigate to albrittonanalytics.com site

4. Find Previous Deployment

   Deploys tab → Published deploys → Identify last working version
   Look for: ✅ Published • [timestamp] • [commit hash]
   

5. Execute Rollback

6. Click on last known good deployment
7. Click "Publish deploy" button

8. Confirm rollback

9. Verification

   # Wait 30-60 seconds then check
   curl -I https://www.albrittonanalytics.com
   # Verify deploy ID matches rolled-back version
   curl -s https://www.albrittonanalytics.com | grep -o "Deploy ID: [a-f0-9]\{24\}"
   

Recovery Time: 2-5 minutes
Risks: May lose recent content updates

3.2 CLI Rollback

# Install Netlify CLI if not available
npm install -g netlify-cli

# Login and select site
netlify login
netlify sites:list
netlify switch

# List recent deployments
netlify api listSiteDeploys --site-id=YOUR_SITE_ID | jq '.[] | {id: .id, state: .state, created_at: .created_at}'

# Rollback to specific deployment
netlify api restoreSiteDeploy --site-id=YOUR_SITE_ID --deploy-id=DEPLOY_ID

4. Git-Based Rollback Procedures

4.1 Revert Last Commit (5-10 minutes)

When to Use: Recent commit caused issues, main branch affected

# 1. Clone/access repository
git clone https://github.com/mattsiler/ultimate-mkdocs.git
cd ultimate-mkdocs

# 2. Identify problematic commit
git log --oneline -10
git show HEAD  # Review latest commit

# 3. Create revert commit
git revert HEAD
git push origin main

# 4. Verify deployment triggers
# Check Netlify dashboard for new build

Verification:

# Confirm revert commit exists
git log --oneline -3
# Should show: revert commit, original commit, previous commit

4.2 Hard Reset Rollback (10-15 minutes)

When to Use: Multiple bad commits, clean slate needed

Destructive Operation

This permanently removes commits. Use with extreme caution.

# 1. Identify target commit (last known good)
git log --oneline -20
git show COMMIT_HASH  # Verify this is the target

# 2. Create backup branch
git checkout -b emergency-backup-$(date +%Y%m%d-%H%M%S)
git push origin emergency-backup-$(date +%Y%m%d-%H%M%S)

# 3. Reset main branch
git checkout main
git reset --hard GOOD_COMMIT_HASH

# 4. Force push (DANGEROUS)
git push --force-with-lease origin main

# 5. Verify deployment
# Monitor Netlify for rebuild

4.3 Branch Restoration

# If main branch is corrupted, restore from backup
git checkout -b main-recovery
git reset --hard origin/backup-branch-name
git checkout main
git reset --hard main-recovery
git push --force-with-lease origin main

5. Content Rollback Procedures

5.1 Individual File Restoration

# Restore specific file from previous commit
git checkout HEAD~1 -- docs/specific-file.md
git add docs/specific-file.md
git commit -m "Emergency: Restore specific-file.md from previous version"
git push origin main

5.2 Directory Restoration

# Restore entire directory
git checkout HEAD~1 -- docs/section/
git add docs/section/
git commit -m "Emergency: Restore docs/section/ directory"
git push origin main

5.3 Content Backup Verification

# List files changed in last N commits
git diff --name-only HEAD~5..HEAD

# Show content differences
git diff HEAD~1..HEAD docs/

6. DNS and Domain Recovery

6.1 DNS Failover

When to Use: Primary hosting down, need immediate failover

Prerequisites: - Backup hosting configured - DNS management access - Backup site ready

# Check current DNS records
dig www.albrittonanalytics.com
nslookup www.albrittonanalytics.com

# Update DNS (varies by provider)
# Example for Cloudflare:
# 1. Login to Cloudflare dashboard
# 2. Navigate to DNS settings
# 3. Update A/CNAME records to backup hosting
# 4. Set TTL to 300 (5 minutes) for quick changes

6.2 SSL Certificate Recovery

# Check SSL certificate status
openssl s_client -connect www.albrittonanalytics.com:443 -servername www.albrittonanalytics.com

# For Netlify SSL issues:
# 1. Netlify dashboard → Domain settings
# 2. SSL/TLS settings → Renew certificate
# 3. Or: Remove and re-add domain

Recovery Time: 5-15 minutes (DNS propagation)
Risks: Brief DNS propagation delay

7. Database/Form Data Recovery

7.1 Netlify Forms Data Recovery

When to Use: Form submissions lost or corrupted

# Export form submissions via Netlify API
curl -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  "https://api.netlify.com/api/v1/sites/SITE_ID/submissions"

# Download specific form data
curl -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  "https://api.netlify.com/api/v1/forms/FORM_ID/submissions" > form_backup.json

7.2 Contact Form Restoration

1. Access Netlify Dashboard
2. Site settings → Forms

3. Export submissions before rollback

4. Backup Process

   # Create backup directory
   mkdir -p backups/forms/$(date +%Y%m%d)
   
   # Export via dashboard or API
   # Manual: Download CSV from Netlify Forms
   

5. Verify Form Functionality Post-Rollback

6. Test form submission
7. Check email notifications
8. Verify spam filtering

8. Performance Degradation Response

8.1 CDN Cache Purging

# Netlify cache purge via API
curl -X POST -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  "https://api.netlify.com/api/v1/sites/SITE_ID/deploys/DEPLOY_ID/restore"

# Manual cache purge:
# Netlify dashboard → Site settings → Build & deploy → Post processing → Clear cache

8.2 Asset Optimization Emergency

# Quick image optimization check
find docs/assets/images -name "*.png" -size +1M
find docs/assets/images -name "*.jpg" -size +500k

# Temporary asset removal for performance
git mv docs/assets/large-files/ docs/assets/large-files-disabled/
git commit -m "Emergency: Temporarily disable large assets"
git push origin main

8.3 Build Performance Issues

# Check build logs in Netlify
# Look for:
# - Plugin timeouts
# - Memory issues
# - Dependency problems

# Quick fix: Disable resource-intensive plugins
# Edit mkdocs.yml temporarily:
sed -i 's/^plugins:/# plugins (disabled):/' mkdocs.yml
git add mkdocs.yml
git commit -m "Emergency: Disable plugins for performance"
git push origin main

9. Security Incident Response

9.1 Compromised Access

Immediate Actions (Within 5 minutes):

1. Revoke Access Tokens

   # GitHub: Settings → Developer settings → Personal access tokens → Delete
   # Netlify: User settings → Applications → Revoke OAuth apps
   

2. Change Passwords

3. GitHub account
4. Netlify account
5. Domain registrar

6. DNS provider

7. Check Recent Activity

# Via Netlify: Site settings → General → Danger zone → Stop auto publishing

# 2. Identify malicious changes
git log --since="24 hours ago" --oneline
git diff HEAD~10..HEAD

# 3. Clean removal of malicious content
git revert MALICIOUS_COMMIT_HASH
# Or hard reset if multiple commits affected

# 4. Security scan before republishing
grep -r -i "script\|javascript\|eval\|iframe" docs/

9.3 Dependency Security Issues
