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

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

BREAKING: Supabase DNS Resolution Failures for .co TLD Users

Status: Identified | Severity: High | Last Updated: Now

What's Down & Who's Affected

Supabase is experiencing DNS resolution failures specifically for users accessing services via .co domain extensions. This primarily impacts:

Projects using *.supabase.co endpoints

Users in regions with DNS caching issues (certain ISPs, corporate networks)

Applications making direct REST API calls to Supabase endpoints

Real-time subscriptions using WebSocket connections

Not affected: Projects using custom domains or accessing via IP addresses directly.

Immediate Workarounds (Deploy These Now)

1. Switch to IP Resolution

Instead of relying on DNS, use Supabase's IP address directly: ```bash

Find your project's IP (check Supabase dashboard > Project Settings > API)

Test with curl:

curl -H "Authorization: Bearer YOUR_ANON_KEY" https://[PROJECT-IP]/rest/v1/ ```

2. Use Custom Domain (Fastest Fix)

If your project supports it, configure a custom domain in Project Settings:

Point api.yourapp.com → Supabase via CNAME

Update your app's SUPABASE_URL environment variable

DNS propagation: ~5-15 minutes

3. Implement DNS Failover

Add fallback logic to your application: ```javascript const supabaseUrls = [ process.env.SUPABASE_URL, // primary 'https://[backup-ip].nip.io', // fallback ];

let supabase; for (const url of supabaseUrls) { try { supabase = createClient(url, anonKey); await supabase.auth.getUser(); // test connection break; } catch (e) { console.log(Trying next endpoint...); } } ```

4. Use Cloudflare/DNS Proxy

Route requests through Cloudflare:

Add Supabase endpoint as origin in Cloudflare

Update your app to use Cloudflare domain

Reduces reliance on .co TLD resolution

How to Check If You're Affected

```bash

Quick diagnostic:

1. nslookup your-project.supabase.co → If no response or timeout: AFFECTED

2. curl -v https://your-project.supabase.co/rest/v1/ → If connection refused: AFFECTED

3. ping your-project.supabase.co → If 100% packet loss: AFFECTED ```

Browser test: Open your app console (F12 > Network tab). Look for failed requests to *.supabase.co with DNS_FAILED errors.

Alternative Tools to Consider

While Supabase resolves this, evaluate:

Firebase Realtime Database — Quick drop-in for real-time features

AWS RDS + API Gateway — More control, higher management overhead

PlanetScale — MySQL alternative, strong DNS infrastructure

Render — Postgres hosting with reliable DNS

Railway — Simple deployment with built-in databases

Note: Switching platforms takes hours/days. Use workarounds above first.

Monitor Recovery

Official channels:

Supabase Status Page: https://status.supabase.com

GitHub Issues: https://github.com/supabase/supabase/issues

Twitter: @supabase

Daily check: ```bash

Monitor from your terminal:

watch -n 60 'dig your-project.supabase.co +short' ```

When it's fixed: You'll see a valid IP address returned from DNS query (not timeout).

---

Bottom line: You have working solutions *right now*. Implement workaround #2 or #3 immediately while Supabase resolves the underlying DNS issue. Most projects should be back to normal within 2-4 hours.

Stay calm. Stay building. 🚀
