Elon Musk's site X and AI tool Grok both appeared to go down Thursday afternoon, according to user reports. While X appears to have recovered, there may still be issues with Grok.

Down Detector showed a spike in user-reported issues for both services starting around 11 a.m. ET. (Disclosure: Down Detector is owned by Ziff Davis, the same company that owns Mashable.)

X appeared to be back up-and-running by about 1 p.m. ET — it worked fine for this writer — but user reports for issues with Grok appeared to continue. It's worth noting that X may have been mostly stable the entire time, but users reported issues with X because Grok is so heavily integrated into the site.

Users on X posted that they got error messages saying Grok was under a heavy load. This comes just after Grok 4 was made free for a limited time.
