Firebase is Google's comprehensive mobile and web application development platform, used by over 3 million apps worldwide. The platform provides real-time database (Firestore and Realtime Database), authentication, cloud storage, hosting, cloud functions, analytics, and push notifications — all through a unified SDK. Firebase is particularly popular for startup MVPs, mobile apps, and real-time applications because it eliminates the need to build and manage backend infrastructure from scratch.
Firebase outages most commonly affect specific services independently. Firestore database outages result from Google Cloud Spanner backend issues or replication lag across regions. Firebase Authentication failures often stem from Google Identity Platform problems. Cloud Functions outages follow Google Cloud Functions infrastructure issues. Firebase Hosting CDN outages are rare but can occur during Google Cloud edge network incidents.
When Firebase goes down, mobile and web apps lose access to their backend data and authentication systems. Real-time features powered by Firestore or Realtime Database stop updating. User login and registration flows break. Push notifications fail to deliver. Cloud Functions that process events or serve API endpoints return errors. For apps built entirely on Firebase, an outage means complete application failure for end users.
Use this page to check Firebase availability. Firebase has many independent services, so Firestore might be down while Authentication works fine. Check status.firebase.google.com for per-service status and Google Cloud's broader status dashboard for infrastructure-level issues.
Firestore issues can be caused by Google Cloud infrastructure problems, regional outages, or quota limits on your project. Check the Firebase console for error rates and quotas. If Firestore queries are timing out across multiple projects, it's likely a platform outage. For project-specific issues, check your security rules and index configuration.
Firebase SDKs include offline persistence for Firestore and Realtime Database, so apps can continue reading cached data during outages. However, writes queue locally and won't sync until service resumes. Authentication tokens remain valid for their duration, but new login attempts will fail. Push notifications will be delayed until Cloud Messaging recovers.
Firebase experiences minor service-specific incidents several times per month, but full platform outages are uncommon. Google's infrastructure provides high reliability for most Firebase services. Firestore and Cloud Functions tend to have the most frequent incident reports, while Hosting and Authentication are generally very stable.
Set up PinusX Uptime Monitor to check your Firebase-hosted app URL and any Cloud Functions API endpoints. You'll receive Slack or email alerts within 60 seconds of any disruption. This provides independent verification separate from Google's own monitoring and status pages.
