Once T399486 is complete, we expect to run the A/A test in production for about one month to collect traffic data.

After a sufficient amount of time has passed, we should disable the A/A test to end the experiment. Afterwards we will have a snapshot of data that we can hopefully use to establish a good baseline for user retention, which we will then use to inform future product decisions. Data analysis work is outside the scope of this epic.

Open Questions

• Are we sure that 1 month (30 days) is the correct amount of time here? Will we determine how long to run the test while the test is running, based on incoming data?
• Do we need to revert T399482's instrument patch?
• Do we need to remove the instrument from the instrument list?

See https://wikitech.wikimedia.org/wiki/Experimentation_Lab/Decommission_an_instrument.

Acceptance Criteria

• A config patch has been merged to disable the test from all participating wikis in production
