Maintenance

If the red banner appeared saying "The site will be coming down shortly for maintenance", then you will have few minutes until it is time to shutdown. It mostly criticized by users.

In the maintenance, if you go any website in ROBLOX will redirected to the maintenance page, it will may be the second maintenance or the third maintenance.

In the game
Sometimes if users still in the game, and respawned during maintenance, their outfit will be a noob outfit, or any outfit. If the script tries to get the content, the script will receive the asset but get redirected to maintenance page then returns without a content.
