What should be done if a landing page does not load due to a server error?

When a landing page does not load due to a server error, the appropriate action is to flag it as Didn't Load. This designation acknowledges that the user experience was adversely affected because the webpage could not be accessed, which is critical in evaluating the quality of the webpage. When a server error occurs, the intended content cannot be delivered to the user, making it impossible for the page to meet the standards expected from a functioning website. Therefore, marking it as Didn't Load accurately reflects the situation and informs further evaluations.

Using this flag helps maintain the integrity of the rating process, as it indicates a technical issue rather than a content-related problem. The other options imply a level of accessibility and quality that is not present when the page fails to load, which is why they are not appropriate in this scenario.
