The official Monarch website appears to have been taken down.
Several very observant Monsterverse fans recently noticed that the Monarch Sciences website no longer appears when it is opened in a web browser. And it now appears that it is safe to say that the website has been taken offline by Legendary/Warner Bros.
One reason that the website may have been taken down is because the companies decided to not use it in Godzilla vs. Kong's marketing. However, it is also entirely possible that the website is just being updated currently and that it will reappear once marketing for the fourth Monsterverse film begins.
If this is indeed the end of the website, then it will mark the conclusion to a site in which numerous fans spent hours studying and monitoring their favorite Titans.
Update: The Monarch Sciences website has now come back online.
