Is X down? Elon Musks social media platform crashes.

X appeared to have crashed on Monday. Elon Musk’s website wouldn’t load for users in the early hours of Monday, either on desktop or mobile.

Down Detector showed a sharp spike in user-reported issues with X starting around 9:30 a.m. ET on Monday. (Full disclosure: Down Detector is owned by Ziff Davis, the same parent company as Mashable.)

I tried to load X on my computer and through the mobile app on my phone, but neither would update or bring in new posts. Folks on other sites, like Bluesky, also posted about the site being down.
