I suggest adding a "LINKS ARE DOWN TRY LATER" message on the downloads page as it would stop people making topics that download links are 404. Here is my 2 cent advice on how to do it you can make a get req to the download page maybe and see the response if its 404 and use a terenary operator to check the response code and say the message if its 404 or do have it blank.
We will still be told that the download does not work. 
Needless.
The **HTTP 404**, **404 Not Found**, **404**, **404 Error**, **Page Not Found** or **File Not Found** [error message](https://en.wikipedia.org/wiki/Error_message) is a [Hypertext Transfer Protocol](https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol) (HTTP) [standard response code](https://en.wikipedia.org/wiki/List_of_HTTP_status_codes), in [computer network](https://en.wikipedia.org/wiki/Computer_network) communications, to indicate that the [browser](https://en.wikipedia.org/wiki/Web_browser) was able to communicate with a given [server](https://en.wikipedia.org/wiki/Server_(computing)), but the server could not find what was requested. The error may also be used when a server does not wish to disclose whether it has the requested information.[[1]](https://en.wikipedia.org/wiki/HTTP_404#cite_note-1)
The website hosting server will typically generate a "404 Not Found" web page when a user attempts to follow a [broken or dead link](https://en.wikipedia.org/wiki/Link_rot); hence the 404 error is one of the most recognizable errors encountered on the [World Wide Web](https://en.wikipedia.org/wiki/World_Wide_Web).
