BREAKING: Fly.io MAJOR 🚨 IPv6 Networking Issues in DFW [wg27hspc94pr]

Fly.io experiencing significant IPv6 networking disruption in Dallas-Fort Worth region. Immediate workarounds and monitoring steps for affected indie hackers.

BREAKING: Fly.io IPv6 Networking Issues in DFW

Status: IDENTIFIED | Severity: MAJOR | Last Updated: NOW

What's Down & Who's Affected

Fly.io is currently experiencing IPv6 networking issues specifically in the DFW (Dallas-Fort Worth) region. This means:

Apps deployed to dfw region experiencing packet loss and connection timeouts

IPv6 traffic affected; IPv4 may have degraded performance

Database connections, external API calls, and inter-app communication potentially impacted

If your app runs in DFW, you're affected. If it runs elsewhere, you're likely fine.

Check your fly.toml: Look for primary_region = "dfw" or DFW in your regions array.

Immediate Workarounds (Do These Now)

Option 1: Disable IPv6 (Fastest Fix)

```bash fly config save --format=toml

Edit fly.toml, add or modify:

[env]

FLY_DISABLE_IPV6 = "true"

fly deploy ```

Option 2: Switch Region (If Acceptable)

```bash

Temporarily redeploy to another region

fly regions add sfo # San Francisco fly regions remove dfw fly deploy ```

This takes 2-5 minutes. Data persistence depends on your setup—Postgres replicas will sync automatically.

Option 3: Failover with Load Balancing

If you have apps in multiple regions, update your DNS/LB to route away from DFW: ```bash fly regions list # Check current setup fly regions add [working-region] fly deploy ```

Option 4: Enable IPv4-Only Mode

Add to fly.toml: ```toml [[services]] protocol = "tcp" internal_port = 8080 force_https = false auto_stop_machines = true auto_start_machines = true [services.concurrency] type = "connections" hard_limit = 100 soft_limit = 80 ```

Then: fly deploy --strategy rolling

How to Check If You're Affected

Quick Check: ```bash fly status

Look at "Instances" section—if DFW instances show failures/restarts, you're hit

fly logs

Search for: "connection refused", "timeout", "unreachable"

```

Terminal Test: ```bash curl -v https://your-app.fly.dev

If hanging or timing out, you're affected

```

Check Fly.io Status: Head to [status.fly.io](https://status.fly.io) for official updates. They'll post DFW-specific incident details there.

Alternative Tools to Consider (If Switching)

Railway.app — Simple, reliable, good for indie projects

Render — Similar to Fly, solid uptime, easier dashboard

Heroku — Still viable for small apps despite cost changes

DigitalOcean App Platform — More control, predictable pricing

Vercel (frontend/serverless only) — Not a direct replacement but solid alternative

Don't panic-migrate. This is likely temporary. Most indie hackers stay put and use workarounds.

Monitor Recovery

1. Watch the status page: [status.fly.io](https://status.fly.io) — refresh every 5 min 2. Join Fly community Slack: #incidents channel has real-time updates 3. Test your app continuously: fly logs --follow to watch for errors clearing 4. Once resolved: Slowly revert workarounds (re-enable IPv6, migrate back to DFW)

Bottom Line

This is a regional issue, not a platform failure. Fly.io's infrastructure is solid. Apply one of the workarounds above *now*, monitor the status page, and you'll be back to normal within 1-2 hours typically.

Stay calm. Your data is safe. This happens to every provider.
