Gmail deletes user accounts: user testing run amok
I wanted to talk about this for a moment because the language Google uses to handle this minor crisis is very good, but the root cause is the very thing that Google prides itself on. Testing.
So what caused this problem? We released a storage software update that introduced the unexpected bug, which caused 0.02% of Gmail users to temporarily lose access to their email. When we discovered the problem, we immediately stopped the deployment of the new software and reverted to the old version.

150,000 users woke up to an empty inbox because they were part of a testing sample. This is routine for large production sites – they continually roll new features out to testing audiences. If Facebook has a new feature, they’ll put it in front of a test audience. As it is, I believe the storage (gmail offline) feature is an opt-in labs option.
It’s great that Google has a backup plan for a catastrophic data collapse. Hopefully they also have backups for the backup of their multiple location redundant data distribution network.
Obviously, Google does not mention anything about user testing or being more careful with its user tests. They are, however, very sorry. This is not to rail against user testing, it is much better that only 0.02% of the population was exposed to this malignant code.
Remember your backups. Only expose beta users to potentially dangerous code. Hey, they signed up for it.
