Event Timeline and Detailed Customer Impact
The issue was introduced when the routing library we use in the UI was updated to the latest version and deployed to our production environment. Whenever the environments change, the code to initialize back the utility was incorrectly placed in the routing flow and didn’t happen in the expected order.
Our automation harnesses on our testing environments have been updated to consider these type of scenarios. These new suites will prevent this type of incident from reaching our customers again.
We would like to apologize to our customers for any impact you may have experienced as a result of this event. We value the trust you've placed in us, and will endeavor to improve on our processes, procedures, and systems.
