BREAKING: Supabase DNS Resolution Failures for .co TLD Users [MONITORING]

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

BREAKING: Supabase DNS Issues Affecting .co TLD Users

What's Happening Right Now

Supabase is currently experiencing DNS resolution failures specifically for users with .co domain extensions. This means if your project domain ends in .co, you may be unable to connect to your Supabase backend via DNS lookups. The status is MONITORING — Supabase infrastructure team is actively investigating.

Who is affected:

Projects using .co TLDs to access Supabase APIs

Users relying on DNS-based connection strings

Direct API calls through custom .co domains

Who is NOT affected:

Direct IP address connections

.com, .io, .dev, and other TLD users (unconfirmed but currently stable)

Projects using Supabase's native *.supabase.co subdomains

---

Immediate Workarounds (Do This Now)

1. Switch to IP-Based Connections

Replace your DNS-based connection string with the direct IP address of your Supabase instance:

``` // Instead of: const { createClient } = require('@supabase/supabase-js') const supabase = createClient('https://your-project.co', 'anon-key')

// Use: const supabase = createClient('https://XXX.XXX.XXX.XXX:443', 'anon-key') ```

Find your IP in the Supabase Dashboard → Settings → API → Host IP address.

2. Use Supabase's Native Subdomain

If you control the connection, temporarily route through: https://your-project.supabase.co

3. Implement DNS Fallback Logic

```javascript const primaryURL = 'https://your-project.co' const fallbackURL = 'https://your-project.supabase.co'

const supabaseURL = process.env.USE_FALLBACK ? fallbackURL : primaryURL ```

4. Update Environment Variables

Push new connection strings to production immediately without DNS resolution.

How to Check If You're Affected

Quick DNS Test: ```bash nslookup your-project.co

If this times out or returns NXDOMAIN → you're affected

Test fallback:

nslookup your-project.supabase.co

Should resolve normally

```

Application-Level Check: ```javascript fetch('https://your-project.co/rest/v1/health') .catch(err => console.log('DNS failure detected:', err.message)) ```

Alternative Tools to Consider (Temporary)

If you need immediate redundancy:

Firebase Realtime Database — quick setup, familiar API

PlanetScale (MySQL) — direct IP connections available

Neon (Postgres) — similar to Supabase, uses .neon.tech domain

MongoDB Atlas — connection string flexibility

⚠️ Don't migrate yet — this is likely to resolve within hours.

This post will be updated as status changes

Automated Checks: ```bash while true; do nslookup your-project.co && echo "✅ Resolved" || echo "❌ Failed" sleep 300 done ```

Bottom Line

This is not a data loss event. Your databases are safe. DNS resolution will recover. Use IP-based connections or the native .supabase.co domain until then.

Stay calm. Stay deployed.
