What is a disadvantage of relying on a website for communication?

Relying on a website for communication has the significant disadvantage that websites can crash, which poses a risk of losing messages or important information. Such technical failures may result from server issues, overloads, or other unforeseen circumstances. When this happens, users may find themselves unable to access their messages or information, leading to interruptions in communication and a lack of continuity in business operations.

In contrast, the other options highlight advantages rather than disadvantages. Websites being easily updatable allows for timely information sharing, while accessibility concerns are generally mitigated by the 24/7 nature of most websites. Additionally, while creating a website can incur costs, there are free options available, making the proactive development of a website often feasible for most organizations. Thus, the risk of crashes stands as a paramount concern when relying on a website for communication purposes.
