Users unable to login to web application, alerts not sending

Final update

All systems are operational again: users can log in, tests are being run, and alerts are being sent. Users should expect alerts for any tests that are currently in a failure state, as well as rolled up schema changes for the duration of the incident period. We are continuing to uncover the root cause and will follow up with details and actions to prevent incidents like this from occurring in the future.
