Google Analytics for Firebase Glitch Crashed Thousands of iPhone Apps

A data formatting error originating from Google's servers triggered a cascade of crashes in numerous iOS and iPadOS applications that use Google Analytics for Firebase. The issue, which occurred on the night of September 28-29, prevented many apps from launching.

The problem stemmed from a malformed data payload sent by Google. When the Firebase component within an app received this incorrect data, it could cause the application to shut down unexpectedly. This occurred at the point of launch.

Google Analytics for Firebase is integrated into apps via an SDK, a development kit used by publishers to monitor application usage. According to reports, this SDK received improperly formatted data from Google's servers, leading to app crashes immediately upon opening. Developers of affected apps had no immediate action to take, as the bug was not within their own code and did not require an App Store update.

Some developers reported tens of thousands of crashes for a single application, illustrating the scale of the disruption. Google has not released an overall figure for the total number of affected users. While Firebase is also available for Android, this specific incident impacted only the Google Analytics SDK for Apple platforms; Android smartphones were unaffected.

The first crashes were noted on September 29 at 2:41 AM Paris time (8:41 AM California time). Google deployed a fix, and the correction was fully rolled out by 4:52 AM Paris time (10:52 AM California time), a total resolution time of 2 hours and 11 minutes. For most users, no action was needed. No downloads or specific steps were required to restore functionality.

However, some devices experienced a longer recovery period. Cached data could have maintained the issue for up to four hours after the fix was deployed. Google indicated that these remaining instances would resolve on their own.
