This is one of the bandwagon feature requests. It can be legitimately useful for popular games on ROBLOX in the event some sort of manual intervention is needed on their part e.g. “Saves are broken – do not play for now.”, but it’s being requested for the wrong reason: “I’m curious”.
“I’m curious” is not a good use case – it tells you what you already know (site taking minutes to load a page or a giant maintenance banner is pretty obvious), and doesn’t solve the issue any faster. The only motive behind this reason is “I can’t do anything about the site being down, but want some sort of hope to make myself feel better” Resources won’t be put into implementing this change for the sake of curiosity. Anyone who wants this feature should tailor their responses to how this could be useful for business-case reasons of popular games.
