Monitoring Guides
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
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.
Read the guide →Developer ToolsVercel
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.
Read the guide →Developer ToolsNetlify
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.
Read the guide →Developer ToolsSupabase
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.
Read the guide →Developer ToolsFirebase
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.
Read the guide →Developer ToolsMongoDB 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.
Read the guide →Developer ToolsTwilio
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.
Read the guide →Developer ToolsSendGrid
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.
Read the guide →Developer ToolsAuth0
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.
Read the guide →Developer ToolsCloudinary
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.
Read the guide →E-commerce
Shopify
Shopify downtime means lost sales. If your storefront, checkout, or admin panel is unreachable, customers can't browse or buy — and you may not know until someone complains.
Read the guide →E-commerceWooCommerce
WooCommerce runs on WordPress, which means it inherits every WordPress failure mode — plus its own. Plugin conflicts, payment gateway timeouts, cart session failures, and database connection limits can break your store while the rest of your WordPress site looks fine. Every minute of checkout downtime is lost revenue.
Read the guide →Communication
Slack
When Slack goes down, team communication stops. Integrations break, bots stop posting, and critical alerts from other tools never arrive. The irony: you can't even tell your team Slack is down... on Slack.
Read the guide →CommunicationDiscord
If you use Discord for community support, team chat, or webhook alerts, an outage means missed messages and lost context. Bot integrations fail silently — no errors, just silence.
Read the guide →Infrastructure
Amazon Web Services
AWS powers a significant portion of the internet. A regional outage can take down your servers, databases, CDN, and storage. AWS's own status page has historically been slow to update during major incidents.
Read the guide →InfrastructureCloudflare
Cloudflare sits between your users and your origin server. If Cloudflare has issues, your site becomes unreachable even if your server is perfectly healthy. DNS failures are especially impactful — your domain simply stops resolving.
Read the guide →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.
Read the guide →Cloud PlatformsDigitalOcean
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.
Read the guide →Cloud PlatformsRender
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.
Read the guide →Cloud PlatformsRailway
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.
Read the guide →Cloud PlatformsFly.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.
Read the guide →Cloud PlatformsHetzner
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.
Read the guide →Automation
n8n
When you self-host n8n, your workflows are only as reliable as your n8n instance. If the server goes down, every automation stops silently — no errors, no alerts, just workflows that quietly don't run. The tasks you automated to be hands-off become the tasks failing without anyone noticing.
Read the guide →AutomationMake
Make is fully hosted, so you can't monitor their servers — but your automations depend on two things you CAN monitor: the webhook endpoints that trigger your scenarios, and the apps those scenarios connect to. When a trigger webhook stops responding or a connected service goes down, your scenarios fail, and Make won't always alert you in time.
Read the guide →AutomationZapier
Zapier is fully hosted, so you monitor what you control: the webhook endpoints that trigger your Zaps and the apps your Zaps connect to. When a trigger stops firing or a connected service goes down, your Zaps quietly stop working — and a broken automation you're relying on is worse than no automation, because you've stopped doing the task manually.
