BREAKING: Supabase DNS Resolution Failures for .co TLD Users — Immediate Workarounds Inside

Supabase experiencing DNS resolution failures affecting .co domain users. Critical workarounds and monitoring steps for indie hackers.

BREAKING: Supabase DNS Resolution Failures for .co TLD Users

What's Down and Who's Affected

Supabase is currently experiencing DNS resolution failures specifically impacting users with .co domain TLDs. This means if your project domain ends in .co, you may be unable to resolve Supabase API endpoints or connect to your database.

Current Status: Monitoring (not a complete outage)

Affected: .co TLD users attempting to:

Connect to Supabase PostgreSQL instances

Call REST API endpoints

Access Realtime subscriptions

Authenticate via Supabase Auth

Unaffected: Users with .com, .io, .dev, and other TLDs are reporting normal operations.

Immediate Workarounds (Do These NOW)

1. Use IP Address Instead of DNS

Replace your DNS-based connection strings with direct IP addresses: ```

Instead of:

api.supabase.co

Use the direct IP (contact Supabase support or check your project settings)

Temporary: Route through a DNS proxy

```

2. Switch to Cloudflare DNS or Quad9

Update your local machine or server DNS resolvers: ```

Cloudflare

1.1.1.1 1.0.0.1

Quad9

9.9.9.9 149.112.112.112 ```

3. Use Environment Variable Overrides

Temporarily hardcode or use an alternative connection method: ```javascript // If DNS fails, fallback to cached IP or proxy const supabaseUrl = process.env.SUPABASE_URL_BACKUP || 'https://[project-id].supabase.co'; ```

4. Implement Retry Logic with Exponential Backoff

Add resilience to your connection attempts: ```javascript const connectWithRetry = async (maxAttempts = 5) => { for (let i = 0; i < maxAttempts; i++) { try { return await createClient(url, key); } catch (e) { await new Promise(r => setTimeout(r, Math.pow(2, i) * 1000)); } } }; ```

How to Check If Your Project Is Affected

1. DNS Lookup Test: ```bash nslookup your-project.supabase.co dig your-project.supabase.co ``` If this fails or returns no records, you're affected.

2. Check Your Domain TLD: Does your connection string use .co? If yes, you're in the affected group.

3. Test Connectivity: ```bash curl -v https://your-project.supabase.co/rest/v1/ ``` If this hangs or returns DNS errors, confirm the issue.

Alternative Tools to Consider (Temporary Relief)

If the outage extends, these are solid temporary alternatives:

Firebase Realtime Database: Quick setup, similar feature set

PlanetScale (MySQL): Zero-downtime deployment, good DX

Neon (PostgreSQL): Drop-in Supabase alternative, excellent uptime

AWS RDS + API Gateway: More complex, but bulletproof

MongoDB Atlas: If you can shift to NoSQL temporarily

How to Monitor Recovery

1. Supabase Status Page: https://status.supabase.com (check for DNS-specific updates) 2. DNS Checker Tool: Use https://dnschecker.org to monitor global DNS propagation 3. Set Up Monitoring: ```bash # Monitor DNS resolution every 30 seconds watch -n 30 'dig your-project.supabase.co' ``` 4. Subscribe to Supabase Incident Updates via their status page 5. Test Your Fallback: Verify workarounds work before relying on them

Stay Calm, Stay Informed

This is not a database data loss issue — your data is safe. This is purely a DNS resolution problem. Most users should see resolution within hours. Use the workarounds above to maintain service continuity.
