BREAKING: Fly.io CDG Region Capacity Issues – Workarounds Inside

Fly.io experiencing capacity constraints in Paris CDG region. Immediate mitigation steps and alternatives for affected indie hackers.

BREAKING: Fly.io CDG Region Capacity Issues

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

---

What's Down & Who's Affected

Fly.io is currently experiencing capacity issues specifically in the CDG (Paris) region. This affects:

Apps explicitly deployed to cdg region

Auto-scaled deployments that route through CDG

Users relying on CDG for EU traffic

New deployments attempting to launch in CDG

Impact: Degraded performance, failed deployments, potential request timeouts in affected region.

Fly.io's status page is tracking this; Fly team reports they're investigating root cause. ETA unknown.

Immediate Workarounds (Do This Now)

1. Redeploy to Alternate EU Region

```bash fly deploy --region ams # Amsterdam (AMS) - nearest alternative

OR

fly deploy --region fra # Frankfurt (FRA) ```

Switch your fly.toml: ```toml app = "your-app" primary_region = "ams" # Change from "cdg" ```

Then: fly deploy

2. Scale Down CDG Instances

If you can't migrate immediately: ```bash fly scale count 0 --region cdg ``` Let other regions handle traffic temporarily. Requests will route to your next-closest region.

3. Enable Multiple Regions

Update fly.toml for redundancy: ```toml [env] FLY_REGIONS = "ams,fra,lhr" ```

Deploy: fly deploy

This distributes load across Amsterdam, Frankfurt, and London.

4. Route Traffic Away

If using Fly's load balancing, update your DNS to exclude CDG temporarily (check your Fly dashboard under "Instances").

How to Check If You're Affected

Step 1: Check your deployed regions ```bash fly status ``` Look for apps showing cdg in the region column.

Step 2: Test endpoint latency ```bash curl -w "@curl-format.txt" -o /dev/null -s https://your-app.fly.dev ``` If timeout or >5s response, likely affected.

Step 3: Check Fly.io official status Visit: status.fly.io → Look for CDG region alerts

Step 4: Monitor logs ```bash fly logs --region cdg ``` Watch for capacity/rejection errors.

---

Alternative Hosting (If Switching)

If you need immediate alternatives:

Render (EU region available, similar pricing)

Railway (Paris support, simpler deployment)

Heroku (EU compliance tier available)

AWS Lightsail (direct region control, lowest latency)

Hetzner Cloud (cheapest EU option, manual setup)

None are drop-in replacements, but all handle EU traffic.

How to Monitor Recovery

Real-time Status

1. Fly.io Status Page: status.fly.io (bookmark it) 2. Twitter: @flydotio for updates 3. Discord: Fly community channel (check pinned messages)

Automated Monitoring

```bash

Check every 60 seconds

watch -n 60 'fly status' ```

Health Check

Once Fly announces recovery, test: ```bash fly deploy --region cdg

Should succeed without timeout

```

---

Bottom Line

Don't panic. This is regional, not platform-wide. Action item: If using CDG, redeploy to AMS/FRA now (2-minute fix). Fly will resolve this, but traffic shifting buys you resilience for future incidents.

Stay calm. Stay deployed. We're in this together.
