BREAKING: Supabase DNS Resolution Failures for .co TLD Users

Supabase experiencing DNS resolution failures affecting .co domain users. Immediate workarounds and status checks inside.

BREAKING: Supabase DNS Resolution Failures for .co TLD Users

What's Down

Supabase is currently experiencing DNS resolution failures specifically impacting users attempting to connect from or to .co TLD domains. This affects:

API Connectivity: Users on .co domains cannot resolve api.supabase.co and related endpoints

Dashboard Access: Web console access may be intermittent for affected users

Database Connections: Direct PostgreSQL connections through Supabase may fail with DNS timeouts

Real-time Features: WebSocket connections dependent on DNS resolution are affected

Status: Under investigation by Supabase monitoring team

How to Check If You're Affected

1. DNS Lookup Test: ```bash nslookup api.supabase.co dig api.supabase.co ``` If these return SERVFAIL or timeout, you're affected.

2. Ping Test: ```bash ping api.supabase.co ``` Timeouts indicate DNS issues.

3. Check Your Domain: The issue appears specific to .co TLD users—verify your domain extension.

Immediate Workarounds

1. IP Address Direct Connection

- Use the direct IP address instead of domain name if available through Supabase dashboard - Note: I'm uncertain if Supabase exposes direct IPs—check your project settings

2. Alternative DNS Servers

```bash # Try Google DNS nameserver 8.8.8.8 nameserver 8.8.4.4 # Or Cloudflare DNS nameserver 1.1.1.1 nameserver 1.0.0.1 ``` Update system DNS or application-level DNS configuration temporarily.

3. VPN/Proxy Route

- Route connections through a VPN with different DNS to bypass local resolution issues - Use proxy services as temporary workaround

4. Localhost Hosts File

- If you have cached IP addresses, add manual entries to /etc/hosts (Linux/Mac) or C:\Windows\System32\drivers\etc\hosts (Windows) - Caveat: I'm uncertain about Supabase's current IP ranges—this may not be practical

5. Switch to Alternative Backend Services (Short-term)

- Firebase/Google Cloud Firestore - AWS Amplify + RDS - PlanetScale (MySQL) - These won't help immediately but consider for critical operations

6. Contact Supabase Support

- File emergency support ticket on Supabase dashboard - Join Supabase Discord community for real-time updates

What We Don't Know (Uncertain Details)

Root Cause: Whether this is Supabase infrastructure issue or upstream DNS provider problem

ETA: Expected resolution timeline

Scope: If this affects only certain Supabase regions or all endpoints

Whether IP-based connections work: Needs verification

Impact on .com/.io/.other TLDs: Likely unaffected, but unconfirmed

Recommendations

1. Immediate: Switch DNS servers and test connectivity 2. Urgent: Contact Supabase support with your .co domain details 3. Monitor: Check [Supabase status page](https://status.supabase.com) for updates 4. Prepare: Have backup database connection strings ready for critical applications
