Check that correct users have access
This alert is triggered by the User monitor task. This task runs a script that verifies only the correct users have access to things like GitHub.
Investigating issues
When the check fails, look at the console logs for the monitor task:
https://deploy.publishing.service.gov.uk/job/user-monitor
When a new person joins, they are added on GitHub, but they still have to open a number of PRs to give themselves access elsewhere (ex: in govuk-puppet).
If they’re new, they might not have gotten to that yet so you should check with them before attempting to remove their access.
Resolving issues
The list of users and their privileges which the User monitor task compares with the status quo is maintained in the govuk-user-reviewer repository. If you have verified that a user has rightfully been granted access, you can request them or their team lead to adjust the data in the repo accordingly.
