Place updated detection?

I saw it in The Quarry, where if the place is updated, it teleports everyone to a different place.

I'm not sure if this is a universe or something, or if it literally can detect if the place is updated.

If anyone knows how this works, can I get a wiki link?

I've done something like this before. Take a look at my script.

local placeid = game.PlaceId
local start = game.MarketplaceService:GetProductInfo(placeid)
local startup = start['Updated']
local isShuttingDown = false

function shutdown()
	isShuttingDown = true
	for i,v in next, game.Players:GetPlayers() do
		v:Kick()
	end	
end

while wait(1) do
	if not isShuttingDown then
		local newinfo = game.MarketplaceService:GetProductInfo(placeid)
		local newup = newinfo['Updated']
		
		if newup ~= startup then
			local m = Instance.new("Message", Workspace)
			m.Text = "This game has been updated! Shutting down server..."
			wait(1.5)
			shutdown()
		end
	end	
end

game.Players.PlayerAdded:connect(function(p)
	if isShuttingDown then
		p:Kick()
	end
end)

Just be careful with this one. It depends on the updated time, and that time updates when you update the description.
