If you refresh the Roblox maintenance page (while it is shutdown temporalily due to an unexplained Service Disruption) a couple of times (or do some command that contains the word trespass in Inspect element mode), you'll end up stepping into Silent Blox, the Roblox equivalent to Silent Hill.
When you managed to get to this specific 'easter egg', the first thing you see in the login screen is that the televisions in the background are now looking withered & turned off with the Roblox logo also looking gray, withered & deteriorated (the rest of the pages will look exactly the same & losing color).
In the home page, your friend list is set to zero and any attempt of looking up a user will bring up no results, even if you look at their profiles through the URLs (it will show the 404 page).
When you joined the games on it, everything will the be the same as the rest of the pages except looking abandoned, deserted and covered in fog & snowflakes(?).
Although i have to warn you to those who want to try this feature, once you reached this secret feature, you can't leave the platform (even if you use task manager or turning off your pc), the only way to escape is to unplug your computer.
Plus, if you spent too much time in Silent Blox the entire platform will switch to the "Otherplatform" variant occasionally, where everything in the site will turn rusty, industrial and hellish with eerie ambience and a siren constantly blarring out.
In this stage, dangerous apparitions will start to appear in the games: Grey Robloxians, Bobble Head Admins, Pyramid Noobs, etc. Make sure to avoid them at all costs if you don't want your Roblox account to get deleted.
Creepy children's drawings will then appear in the decal section of the library, which displays strange people & look like the drawings were vandalized
Also, if you see a username by the name of "Alessa", avoid contacting with her & leave the game immediately, do not reply to her messages and/or chat logs.
If you wish to try out this feature, then go ahead at your own risk but be careful because it messes up computers very badly, of course.
Safety in maintenance.
