Rblx.co

rblx.co is a Roblox subdomain that was first used on August 15, 2019. It is used as a URL shortener by Roblox employees to shorten URLs for promotions, specifically used on their Twitter and Instagram accounts. Most of the time, these links are for games. However, they can also be used for blog posts, or sometimes even avatar shop items. Visiting the domain directly will link to the home page. The same applies if the user tries to go to something that has not yet been shortened (i.e. https://rblx.co/test will redirect to the home page). However, visiting any of the subdomains will lead to a different location.

The oldest link is LakeShowcase, created on August 15, 2019, at 12:05 PM. There is no official announcement regarding the ownership of the rblx.co domain.

Trivia

 * Flee the Facility and Star Sorority are the only games to receive more than one rblx.co link.
 * Flee the Facility's links are https://rblx.co/1B-Flee-the-Facility and https://rblx.co/flee-the-facility.
 * Star Sorority's links are https://rblx.co/starsorority and https://rblx.co/star-sorority.
 * https://rblx.co/ghostsim-liveops and https://rblx.co/liveops-towerdefenders are the only rblx.co links to contain the word "liveops" in them.
 * For the Build It, Play It: The Island of Move event, the link https://rblx.co/moveit was mentioned in a GUI in-game. Going to this redirects to the home page, which means it is likely a Roblox employee forgot to create a shortened URL at that address.
