What Happens When Your Tools Go Down

Role-by-role survival guides for the services your team depends on. What actually happens, what it costs, and how to detect it in 60 seconds.

Developer Tools

Developer Tools

GitHub

GitHub outages affect CI/CD pipelines, pull request workflows, and deployments. If your team ships code through GitHub, an outage can halt your entire development process.

Vercel

If you host on Vercel, your production site lives on their infrastructure. A Vercel outage means your users see errors — and you need to know before they tell you.

Developer Tools

Netlify

If you deploy to Netlify, your production site depends on their CDN and build system. A Netlify outage can make your site unreachable or prevent new deployments from going live.

Developer Tools

Supabase

Supabase projects can pause after inactivity on the free tier, and even on paid plans, database connection limits, edge function cold starts, and auth service issues can silently break your app. Since Supabase powers your backend, an outage there means your entire application stops working.

Developer Tools

Firebase

Firebase services are independent — Firestore can be down while Auth works fine, or Cloud Functions can timeout while Hosting serves pages normally. Since Firebase apps typically depend on multiple services simultaneously, a partial outage breaks your app in ways that are hard to diagnose without monitoring each piece.

MongoDB Atlas

Atlas manages your database, but managed doesn't mean immune. Free and shared clusters pause after inactivity, connection limits get exhausted, and slow queries can grind your app to a halt. When your database becomes unreachable, your entire application stops working — and Atlas won't proactively tell you.

Twilio

Twilio powers critical flows — SMS verification codes, two-factor authentication, appointment reminders, alerts. When Twilio has issues, your users can't receive login codes, your notifications silently fail, and you may not notice until signups drop or complaints roll in.

Developer Tools

SendGrid

Email is invisible when it fails. A password reset that never arrives, a receipt that doesn't send, a notification stuck in a queue — none of these throw an error your users see. They just silently don't happen. When SendGrid has API issues or deliverability problems, your transactional email breaks without a single visible error.

Developer Tools

Auth0

Auth0 is a total single point of failure. When your authentication provider is down, nobody can log in — not your users, not your admins, not anyone. Your app might be perfectly healthy, but if users can't authenticate, it's effectively down. Auth outages are among the highest-impact failures any app can experience.

Developer Tools

Cloudinary

Cloudinary delivers the images and videos that make up most of what your users see. When its CDN or transformation API has issues, your site loads but images break — blank spaces, broken thumbnails, missing product photos. For visual sites and stores, broken media is nearly as bad as being fully down.

Cloud Platforms

Cloud Platforms

Heroku

Heroku dynos restart every 24 hours, and free/eco dynos sleep after 30 minutes of inactivity. Even on paid plans, deployments cause brief restarts and routing layer issues can silently drop requests. If your app runs on Heroku, you need to know when those restarts cause real downtime.

Cloud Platforms

DigitalOcean

DigitalOcean gives you raw infrastructure, not managed uptime. Your droplet can crash, your database can run out of connections, your load balancer can misconfigure — and DigitalOcean won't tell you. You're responsible for knowing when your services are down.

Cloud Platforms

Render

Render's free tier spins down services after 15 minutes of inactivity, causing cold starts that can take 30+ seconds. Even on paid plans, deployments cause brief downtime, and Render's infrastructure can have regional issues that affect your specific service without triggering a platform-wide incident.

Cloud Platforms

Railway

Railway abstracts away infrastructure, but abstraction doesn't mean immunity. Deployments cause brief restarts, services can crash without visible errors in the dashboard, and resource limits can silently throttle your app. If your users depend on your Railway-hosted service, you need external eyes on it.

Cloud Platforms

Fly.io

Fly.io runs your app across multiple regions, which is great for performance — but it also means failures can be regional. Your app might be down in Frankfurt but running fine in Chicago. Without multi-region-aware monitoring, you'd never know half your European users can't reach your service.

Cloud Platforms

Hetzner

Hetzner gives you raw servers at great prices, but that means you're responsible for everything running on them. There's no managed application monitoring, no auto-restart for crashed processes, and no proactive notification when your app stops responding. If your process dies at 2 AM, nobody knows until someone checks.
