Place it at the start of a waiting scene, then follow it with the Roblox Oof when the connection fails, and add the Pop Sound Effect when the page finally opens.
About this sound
This is a brief internet connecting sound lasting about three seconds, made from electronic tones that signal a connection forming. It feels familiar and slightly tense, like waiting for a page to load, and it works because that small wait is instantly recognisable to anyone who has sat through a slow connection.
