What should you do if a webpage has a server error and no other content is visible?

When encountering a webpage that displays a server error and no content is visible, the appropriate action is to flag it as Did Not Load. This is because a server error indicates a significant issue preventing the webpage from functioning correctly. Users expect to access content reliably, and a server error indicates that the page is unavailable, failing to meet basic expectations for website performance.

Flagging it as Did Not Load appropriately communicates that the webpage did not deliver any usable content or functionality, aligning with the criteria for evaluating the effectiveness and accessibility of a webpage. This action accurately captures the experience of the user, who is unable to access any information or resources from the page due to the server error condition.
