BREAKING: Fly.io MINOR 🔴 IPv6 Networking Issues – Workarounds Inside [mq8k17gpg79h]

Fly.io experiencing IPv6 networking disruption. Partial service impact. Immediate workarounds for indie hackers and what to do right now.

BREAKING: Fly.io IPv6 Networking Issues – What You Need to Know

Status: MINOR – Partial Disruption (Monitoring) Severity: 🔴 Limited Impact Last Updated: Now

---

What's Down & Who's Affected

Fly.io is currently experiencing IPv6 networking degradation affecting connectivity to applications deployed on their platform. This is not a complete outage.

Affected:

Apps with IPv6-only or IPv6-primary configurations

External connections routing through IPv6 addresses

Some cross-region traffic (limited scope)

NOT Affected:

IPv4 connectivity remains stable

Most standard deployments continue normal operation

Internal Fly.io networking (IPv4)

---

Immediate Workarounds – DO THIS NOW

1. Force IPv4 Routing (Fastest Fix)

If your app supports dual-stack, your client requests should naturally fall back to IPv4. Verify by checking your app logs:

``` grep -i "ipv6\|::\|2001:" your-logs.txt ```

If seeing IPv6 traffic: instruct clients to explicitly use IPv4 endpoints or disable IPv6 in your DNS records temporarily.

2. Update Your DNS Records

If using Fly.io's default DNS:

Remove AAAA records (IPv6) temporarily

Keep A records (IPv4) intact

TTL: Set to 5 minutes for quick rollback

```bash

Check current records

dig yourdomain.com AAAA dig yourdomain.com A ```

3. Fly.io CLI Check

```bash fly status fly logs --tail ```

If apps show GREEN status but connections lag, this confirms the IPv6 issue.

4. Failover to Secondary Region

If critical: scale to a secondary region temporarily: ```bash fly regions add ord # Add another region fly scale count=2 ```

How to Check If YOUR Project Is Affected

3-Point Diagnostic:

1. Endpoint Test ```bash curl -6 https://yourapp.fly.dev # IPv6 test curl -4 https://yourapp.fly.dev # IPv4 test ``` If IPv6 is slow/timeout and IPv4 works: you're affected.

2. Check Fly.io Status Page Visit: status.fly.io – filter for "Networking"

3. User Reports Monitor Fly community Slack #incidents or their status updates. Most users won't notice.

Alternative Tools to Consider

If you need immediate redundancy:

Railway.app – quick IPv4 deployment

Render.com – stable alternative

Hetzner Cloud – lower-level control, more setup

DigitalOcean App Platform – proven reliability

Note: No need to migrate yet. This is monitoring status.

Monitor Recovery

Real-Time Updates:

Fly.io Status Page: status.fly.io (bookmark it)

Twitter: @flydotio

Fly Community Discord: #incidents

Verify Resolution: ```bash

Run every 5 minutes until stable

time curl -6 https://yourapp.fly.dev ```

Look for: consistent sub-100ms response times.

---

Bottom Line

✅ Your app likely still works on IPv4 ✅ Workaround: Force IPv4 routing ✅ Monitor status page, don't panic-migrate ✅ Fly.io team is actively monitoring

Stay calm. This is a network layer issue, not a platform failure. Most indie projects won't see impact. Follow the diagnostics above and report findings to Fly support if critical.
