Which is NOT available to you whenever OCI creates or resolves an incident?

Whenever Oracle Cloud Infrastructure (OCI) creates or resolves an incident, users receive certain types of notifications to keep them informed about the status and updates related to their services. Text message notifications and email notifications are standard methods of communication that ensure users are promptly alerted about incidents.

The option referring to "Without Notification" indicates a scenario where no form of communication is sent, which could happen depending on the user's notification settings, but it does not represent a permanent unavailability of a notification method—it's a condition rather than a method.

Twitter notifications, however, are not a standard form of communication concerning OCI incidents. While other companies might use social media for customer engagement or updates, OCI primarily utilizes more direct and reliable forms of notifications like email and text messages to ensure that users receive critical information in a timely manner. Therefore, Twitter notification is not available as a method of incident communication within OCI.
