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

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

BREAKING: Supabase DNS Resolution Failures for .co TLD Users

Status: MONITORING | Last Updated: Now

---

What's Down and Who's Affected

Supabase is currently experiencing DNS resolution failures specifically for users with .co top-level domains (e.g., yourproject.co). This affects:

Projects using .co domain names connecting to Supabase

API calls attempting to resolve Supabase endpoints via .co domains

Some regional users whose DNS resolvers are routing through affected nameservers

What's working: Supabase .com projects, direct IP connections, and internal infrastructure remain operational.

Scope: This is NOT a full outage. Your data is safe. Authentication and database operations continue normally—the issue is DNS routing only.

---

Immediate Workarounds (Deploy These NOW)

1. Use IP-Based Connections (Fastest Fix)

``` Instead of: supabase-project-name.co Use direct IP or query Supabase's API gateway directly ```

2. Switch to .com Alias (If Available)

If you own both .co and .com versions:

Temporarily redirect traffic to your .com domain

Update your Supabase connection strings

This takes 5 minutes to implement

3. Use Alternative DNS Resolvers

Force your application to use Google or Cloudflare DNS: ```javascript // Node.js example const dns = require('dns'); dns.setServers(['8.8.8.8', '8.8.4.4']); // Google DNS ```

4. Implement Retry Logic with Exponential Backoff

Temporary measure while DNS stabilizes: ```javascript const retryConnection = async (maxRetries = 3) => { for (let i = 0; i < maxRetries; i++) { try { return await supabaseClient.from('table').select(); } catch (error) { await new Promise(r => setTimeout(r, Math.pow(2, i) * 1000)); } } }; ```

How to Check If Your Project Is Affected

Run this diagnostic:

```bash

Test DNS resolution

nslookup your-project.co dig your-project.co

Check if direct IP works

curl -I https://[supabase-ip]/health

Verify Supabase status

curl https://status.supabase.com/api/v2/status.json ```

If nslookup returns "NXDOMAIN" or "timed out," you're affected.

Alternative Tools to Consider

While NOT necessary (this will resolve), consider for future redundancy:

Firebase Realtime Database – Instant fallback option

PlanetScale – MySQL-based, reliable DNS handling

MongoDB Atlas – Proven DNS stability

AWS RDS + API Gateway – Enterprise-grade with global DNS

Our recommendation: Stay with Supabase. This is temporary and Supabase's team is actively resolving. Don't migrate unless you're already planning to.

How to Monitor Recovery

1. Watch Supabase Status Page: https://status.supabase.com 2. Set up alerts: ```bash # Check every 5 minutes watch -n 300 'nslookup your-project.co' ``` 3. Join Supabase Discord – Real-time updates in #incidents 4. Monitor your logs – Watch for DNS timeout errors clearing

What You Should Do RIGHT NOW

✅ Deploy workaround #1 or #2 (takes <15 minutes) ✅ Test your connection with the diagnostic commands ✅ Set up monitoring ✅ Notify your team ✅ Revert changes once DNS resolves (Supabase will announce all-clear)

This is contained. Your data is safe. You've got this.
