What are the best practices for rolling back a bad update?

Have a tested rollback path ready before you need it (the time to figure out how to roll back is before a bad update, not during, so prepare and test the path so you can revert fast when needed rather than scrambling). Decide your trigger in advance (what bad looks like, e.g. the new version's crash rate clearly worse than the old build), so you act on data rather than debating while players are affected. Roll back fast to stop the bleeding before perfecting a fix, since speed limits how many players the bad update affects, mitigation (stopping the harm) comes before the proper root-cause fix. Verify the rollback resolved the problem (the crash stopped on the reverted build), so you confirm the bleeding stopped. And communicate with players that you addressed it, to preserve trust while you fix the root cause properly. A good rollback reverts players to a known-good build quickly, limiting the damage of a bad update while you fix properly, so the practices serve being prepared (tested path ready), decisive (predefined trigger, fast action), and thorough (verify and communicate), which together turn a bad update from a spreading disaster into a quickly-contained, recoverable event.

When should I roll back instead of hotfixing?

Roll back when you need to stop the bleeding fast and a known-good previous build is available, which is usually the case during an active incident, while a hotfix is better once the immediate harm is stopped and you can fix properly. The key difference is speed and risk: rolling back reverts players to a build you know works, immediately ending the problem, whereas a hotfix takes time to write, test, and ship, during which players keep being affected, and a hotfix written under the pressure of an active incident risks being rushed, incomplete, or introducing new problems. So during a bad update that's actively harming players, roll back first to stop the bleeding (it's the fastest, safest mitigation), then once players are on the stable build and no longer being hurt, diagnose and fix the root cause calmly and ship a proper update without pressure. Prefer rollback when: the problem is serious enough that you need to stop it immediately, a known-good previous build is available to revert to, and rolling back is feasible on your platform. Prefer (or fall back to) a hotfix when: rollback isn't possible (some platforms or changes make reverting hard), or the problem is contained enough that a fast, narrowly-scoped fix is safe and quick. But the general principle during an incident is mitigate first with whatever's fastest, which is usually a rollback, then fix properly afterward, so rolling back is typically the better first response to a bad update that's actively causing problems, with the proper hotfix or update coming after the bleeding is stopped. This is why having a tested rollback path ready is a best practice, so that fast mitigation is available when you need it.

How do I roll back a bad update quickly?

Have the rollback prepared and tested in advance, decide your trigger ahead of time, and act decisively on data when it fires. The biggest factor in rolling back quickly is preparation: before any release, have a tested rollback path, knowing exactly how to revert players to the previous known-good build, so that when a bad update happens you can execute the rollback immediately rather than spending precious time figuring out how while players are affected. Decide your rollback trigger in advance (for example, the new version's crash rate clearly worse than the previous build by some threshold), so the moment your monitoring shows the update is bad, you act on the predefined criteria rather than debating whether it's bad enough, which wastes time during which more players are hurt. Fast detection enables fast rollback: per-version crash monitoring with alerts pages you within minutes when the new version spikes, so you know quickly that a rollback is needed, rather than discovering the bad update hours later. When the trigger fires, roll back fast to the known-good build to stop the bleeding, prioritizing stopping the harm over perfecting a fix (you fix the root cause properly afterward). Then verify the rollback resolved the problem (per-version tracking confirms the crash stopped on the reverted build) and communicate with players. So rolling back quickly is mostly about being ready before you need it, a tested path, a predefined trigger, and fast monitoring to detect the bad update, so that when one happens, you can detect it in minutes and execute a prepared rollback decisively, reverting players to the stable build fast and limiting the damage. The opposite, improvising a rollback under pressure without preparation or clear criteria, is slow and risky, which is why the preparation, having a tested rollback ready and a trigger decided, is the key to rolling back quickly when a bad update inevitably happens.

Best Practices for Rolling Back a Bad Update

Quick answer: Have a tested rollback path ready before you need it, decide your trigger in advance, roll back fast to stop the bleeding, verify it resolved the problem, and communicate. A good rollback limits a bad update's damage.

When an update goes bad, rolling back fast is often the best way to stop the bleeding. Here are the best practices for rolling back a bad update.

Have a Tested Rollback Path Ready Before You Need It

The time to figure out how to roll back is before a bad update, not during, so have a tested rollback path ready. A prepared, tested path means you can revert fast when needed, rather than scrambling to figure out how while players are affected.

Bugnet's per-version tracking confirms which build is good to roll back to. Having a tested rollback path ready before you need it is what makes a fast rollback possible, since a rollback you have to improvise under pressure is slow and risky.

Decide Your Trigger in Advance and Roll Back Fast

Decide in advance what bad looks like (e.g. the new version's crash rate clearly worse), so you act on data not debate, and when triggered, roll back fast to stop the bleeding before perfecting a fix. Speed limits how many players the bad update affects.

Bugnet tracks crash rate per version, giving you the data to trigger on. Deciding your trigger in advance and rolling back fast is what limits a bad update's damage, by acting decisively on data rather than debating while players are hurt.

Verify the Rollback Resolved the Problem and Communicate

After rolling back, verify the problem actually resolved (the crash stopped on the reverted build), and communicate with players that you addressed it. Verification confirms the bleeding stopped, and communication preserves trust while you fix the root cause properly.

Bugnet's per-version tracking confirms when the rollback resolved the problem. So practice rolling back a bad update by having a tested path ready, deciding your trigger in advance and rolling back fast, and verifying and communicating, reverting players to a known-good build quickly to limit a bad update's damage.
