Twitter appears to be restricting access to its platform for anyone not logged into an account.

People without a Twitter account or who weren't logged in used to be able to scroll the platform's homepage and view public accounts and tweets. But as of this week, when such a user opens the platform they are met with a screen prompting them to sign up or sign in to Twitter.

Internet users began noticing the change late this week, and on Friday, multiple CNN reporters were unable to access Twitter without logging in.

It was not immediately clear whether the change was an intentional policy update or a glitch, both of which have been common at Twitter since Musk took over the platform. Twitter did not respond to a request for comment.

The change comes as billionaire owner Elon Musk attempts to revamp Twitter's business following months of challenges since his takeover late last year — now with the help of new CEO Linda Yaccarino.

Twitter's leadership is urging advertisers to return to the platform after many fled over concerns about increased hate speech, layoffs and general questions about the company's direction. Musk has also sought to grow subscription revenue by offering a blue verification checkmark for users who sign up for its Twitter Blue service.

The restriction on public access to Twitter could be an effort to grow the platform's user base, which has always been significantly smaller than social media rivals like Facebook and Instagram.
