How do I know if an update is bad?

Compare the new version against the previous one and watch the timing. The clearest sign is a crash rate that spikes right after release as players adopt the new build, since a spike coinciding with the update strongly implicates it. Also watch for new crash signatures that didn't exist before the update (a failure mode your previous builds never had, almost certainly introduced by the update) and, definitively, the new version performing worse than the previous build, a higher crash rate, more errors, or worse engagement than the build it replaced. If you compare the new build against the last and it's worse, the update regressed, which is the essence of a bad update. To see these signs, you need to monitor per version: per-version crash tracking shows the new build's crash rate against the previous one (revealing if it's worse), catches new signatures on the new build, and, with alerts, surfaces the spike in minutes. Without per-version monitoring, a bad update hides in aggregate data and you discover it days later from reviews, so the key to knowing fast is comparing the new version's health against the previous build right after release.

How fast can I tell if an update is bad?

Within minutes, if you have per-version crash monitoring with alerts set up before you release. The new build's crash rate climbing above the previous version's is the clearest, earliest signal, and an alert on that fires as soon as enough players have updated to show the trend, typically minutes after the bad update starts spreading, not hours or days. This requires per-version tracking (so you're comparing the new build against the previous one, which isolates the 'did this update make things worse' signal) and alerting (so a crash-rate spike on the new version pages you automatically rather than requiring you to watch). With these in place, a bad update triggers an alert within minutes of shipping as the new build's crash rate spikes above the old build's among the players who've updated, so you catch it while it's affected only a small fraction of players and can roll back or hotfix before it spreads. This is dramatically faster than the alternative of discovering the bad update from a pile of reviews and complaints, which could be hours or days later, by which point the bad update has crashed for a large share of your base. The speed matters because a bad update's damage scales with how many players the bad build reaches, so catching it in minutes (and rolling back) contains it to few players, while catching it days later means it has already done widespread damage. So you can tell an update is bad within minutes by monitoring crash rate per version with alerts, which surfaces the bad update's crash-rate spike fast, the key is having that monitoring in place before you release, not setting it up after.

What should I do if I shipped a bad update?

Stop the bleeding fast, usually by rolling back if you can, then fix the root cause properly. The priority once you've identified a bad update is to limit how many players the bad build reaches and how long they're exposed, so the fastest mitigation is often to roll back to the previous known-good build, which immediately ends the problem by reverting players to a build you know works, while a hotfix takes time to write and ship during which players keep being affected. So if a rollback is possible, do that first to stop the bleeding, then diagnose the cause of the bad update calmly (per-version crash data shows you the new crash signatures and what regressed) and ship a proper fix without the pressure of an active problem. If rollback isn't possible, ship a fast, narrowly-scoped hotfix instead, but the principle holds: mitigate first (stop the harm), fix properly second. Throughout, communicate with players, acknowledge the problem so they know you're aware and working on it, since how you handle a bad update affects trust as much as the technical fix. And learn from it: a bad update is usually a regression that slipped through, so consider what testing (a regression pass) or process (staged rollout, per-version monitoring) would have caught it, to prevent the next one. Per-version tracking also lets you verify that your rollback or fix actually resolved the problem (the crash rate returns to normal on the reverted or fixed build). So the response to a bad update is: catch it fast (per-version monitoring), stop the bleeding fast (roll back if you can), communicate, fix the root cause properly once stabilized, and improve your process to prevent recurrence, the same incident-response discipline that limits the damage of any bad release.

Signs Your Game Has a Bad Update

Quick answer: Watch for a crash rate spiking right after release, new crash signatures that didn't exist before, a wave of complaints after the update, and the new version performing worse than the last. A bad update shows up fast per version.

A bad update, one that introduces crashes or breaks something, can turn an improvement into a problem affecting your whole player base. Here are the signs your game has a bad update.

A Crash Rate That Spikes Right After Release

The clearest sign is timing: a crash rate that jumps right after you ship an update, as players adopt the new build. A spike that coincides with a release strongly implicates that release, since the crashes started when the new build went out, this is the unambiguous early signal of a bad update.

Bugnet tracks crash rate per version and alerts on spikes, so a post-release spike is caught fast. A crash rate spiking right after release, tied to the new version, is the fastest and clearest sign of a bad update, but you only catch it early if you're monitoring per version, otherwise you learn from reviews days later.

New Crash Signatures That Didn't Exist Before

A bad update often introduces a new crash signature, a failure mode your previous builds never had. So a sign is new signatures appearing after the release: a crash that didn't exist before the update and does after is almost certainly introduced by it, pointing directly at the update as the cause.

Bugnet groups crashes by signature and tracks per version, so a new signature on the new build stands out. New crash signatures appearing right after an update are a strong sign of a bad update, catching the case where the update introduced a new failure mode rather than just worsening an existing crash.

The New Version Performing Worse Than the Previous Build

The defining sign is comparison: the new version performing worse than the build it replaced, a higher crash rate, more errors, worse engagement. If you compare the new build against the previous one and it's worse, the update regressed, which is the essence of a bad update. Without per-version comparison, this hides in the aggregate.

Bugnet tracks crash rate per version, so comparing the new build against the previous one is direct. The new version performing worse than the last is the definitive sign of a bad update, and per-version comparison is what makes it visible, since an aggregate that blends versions would hide the regression.

Watch for a crash rate spiking right after release, new crash signatures that didn't exist before, a wave of complaints after the update, and the new version performing worse than the last. A bad update shows up fast per version.
