Former President Donald Trump‘s planned interview Elon Musk got off to a difficult start on Monday as Musk claimed that a cyberattack prevented users from accessing the interview on X, formerly Twitter.

Both Trump and Musk, who purchased the platform in late 2022 and has endorsed the former president, teased the “talk” on X Spaces extensively before it was set to take place at 8 p.m. Eastern Time on Monday.

However, when the time came, the link displayed only a “Space Not Available” message for most users. It was unclear whether or not the conversation started, as the Spaces link was still inaccessible as of 8:23 p.m Eastern Time.

Musk claimed that a cyberattack was to blame in a post at 8:18 p.m., writing the following: “There appears to be a massive DDOS attack on X. Working on shutting it down. Worst case, we will proceed with a smaller number of live listeners and post the conversation later.”

This is a developing news story and will be updated with more information.
