Thousands of users across the United States reported disruptions to ChatGPT and Claude on June 23, in a brief outage that affected access to major artificial intelligence services.

According to outage-tracking data from DownDetector, both platforms experienced spikes in user complaints within a short time window, before services were restored roughly an hour later.

OpenAI’s ChatGPT began showing signs of disruption at around 15:45 local time. Reports of issues peaked at 17:45, when around 230 user complaints were recorded.

The majority of those affected (83%) said they were unable to access ChatGPT, while a smaller share reported problems with Codex. Outage maps indicated clusters of reports in major US cities including New York, Boston, Washington, San Francisco and Los Angeles.

Anthropic’s Claude service experienced a similar but shorter disruption, beginning at approximately 16:53 and lasting until around 17:23. During that period, a sharp spike of 7,246 reports was recorded at the height of the outage. Of these, 43% related to Claude Chat, 25% to the mobile application, and 24% to Claude Code.

Both companies’ services were restored later the same day. The cause of the disruptions has not yet been confirmed.
