BREAKING: Fly.io MAJOR 🚨 IPv6 Connectivity Issues in EWR – Workarounds Inside

Fly.io experiencing significant IPv6 connectivity disruption in Newark region. Immediate workarounds and monitoring guidance for affected indie hackers.

BREAKING: Fly.io IPv6 Connectivity Issues – EWR Region 🚨

Status: Monitoring | Severity: MAJOR | Affected Region: Newark (EWR)

What's Down & Who's Affected

Fly.io is currently experiencing IPv6 connectivity issues in the Newark (EWR) region. This means:

Affected: Apps deployed to EWR with IPv6 enabled or requiring IPv6 connectivity

Impact: Connection timeouts, DNS resolution failures for IPv6 clients, degraded performance for users accessing via IPv6

Unaffected: IPv4 connections, other regions (SFO, LHR, SYD, etc.), apps with IPv4-only configuration

This is not a complete outage—IPv4 users and other regions are functioning normally.

Immediate Workarounds (Do This Now)

Option 1: Disable IPv6 (Quickest Fix)

Update your fly.toml: ```toml [env] DISABLE_IPV6 = "true" ``` Then: fly deploy

This forces IPv4-only routing. Deploy takes ~2-3 minutes.

Option 2: Switch to Different Region (5 min)

If your app supports it, redeploy to an unaffected region: ```bash fly regions add sfo # or lhr, syd fly deploy --region sfo ``` Update DNS/load balancer pointing if needed.

Option 3: Enable Regional Failover

Add a secondary region in your deployment: ```bash fly scale count 1 --region sfo ``` Your app will auto-distribute traffic if EWR remains degraded.

How to Check If You're Affected

Run these diagnostics:

```bash

Check your app's deployed regions

fly regions list

Test IPv6 connectivity

fly ssh console curl -6 https://www.google.com # If this hangs = affected

Check logs for IPv6-related errors

fly logs --region ewr ```

If you see timeouts or connection refused on IPv6 tests → you're affected.

Alternative Hosting (Consider If Prolonged)

If EWR issues persist beyond 2 hours:

Railway.app — Similar DX, quick region switching

Render — Reliable, good for Node/Python apps

Heroku (legacy but stable) — If you need guaranteed uptime

AWS Lightsail/EC2 — More control, slight complexity increase

Hetzner Cloud — Budget option, excellent performance

Pro tip: Don't migrate yet. Fly usually resolves regional issues within 30-90 minutes. Only migrate if you see status page updates indicating extended ETA.

Monitor Recovery

Official Status

Check: status.fly.io (refresh every 5 min)

Self-Monitor

Set up a simple health check: ```bash watch -n 30 'fly status | grep ewr' ```

Or monitor logs: ```bash fly logs --region ewr --follow ```

Look for: IPv6 error rate dropping, latency normalizing.

Summary

✅ Immediate action: Disable IPv6 or switch regions (5 min) ✅ Monitor: status.fly.io + your app logs ✅ Don't panic: IPv4 is fine, other regions unaffected ✅ Wait 30-90 min before considering migration

We're tracking this. Updates will post here and on Fly's status page.
