The joint X Spaces event of Elon Musk and Donald Trump crashed Monday afternoon. The 5 p.m. PT conversation of the owner of X with the former president was scheduled; users who tried to join at that time received an error message.
"This Space is not available," said a message on X while trying to join the Space.

The highly anticipated conversation — touted by Trump and Musk as the former U.S. president's return to X — started at 5:42 p.m. PT, following a "conversation" that Musk unveiled. The live event, which was advertised as beginning at 5 p.m. PT, was an hour and 42 minutes later.
The former president returned to the social media outlet Monday morning, when his first posts appeared since January 2021, when he was banned from the platform. Among his Monday posts were some that further discussed the conversation he has with Musk, while others were campaign ads and links to his former presidential website. For the last three years, Trump has mostly posted on his own social media hub Truth Social. Which is all well and good, but Trump's been free to tweet on X nearly two years; a month after Musk bought Twitter, now X, this social media outlet reinstated Trump's Twitter account in November 2022.
Musk said "a massive DDoS attack on X" apparently occurred, supposedly causing the crashed X Space. The owner of X says that social media platform ran extensive testing today with 8 million concurrent listeners. Musk kicked off the Space interview by linking the supposedly launched DDoS attack — which stands for "distributed denial-of-service," in which a bad actor overwhelms an internet server with a flood of artificial traffic — to his opposition to hearing the former president.

As this massive attack illustrates, there's plenty of resistance to have people just hear what President Trump has to say and so, but I'm honored to have this conversation, ended up starting the Spaces, which will provide a discussion of the current state of society.

It's not the first time an X Space has crashed when a political campaign tried to use the platform. In May 2023, technical issues on Twitter scuttled Ron DeSantis's launch of his 2024 campaign in the middle of a Twitter Space session featuring Elon Musk and venture capitalist David Sacks.
