Claude Down: Anthropic Provides Update as Thousands Report Outages

Anthropic said widespread technical problems disrupted access to its Claude artificial intelligence platform Wednesday morning, with users reporting login failures and errors across Claude.ai, the company's application programming interface and Claude Code.

According to the company's official status page, Anthropic began investigating elevated error rates shortly before 11 a.m. Eastern time.

Outage-tracking website Downdetector showed a sharp spike in complaints about Claude beginning Wednesday morning. More than 7,000 users had reported problems by about 8:02 a.m. Pacific time, with reports climbing rapidly throughout the morning. The total surpassed 15,000 within about 25 minutes and later exceeded 20,000, according to Downdetector, which collects user-submitted reports from multiple sources. Most complaints cited problems accessing Claude Chat, along with login failures and connectivity issues.

In an update posted at 12:29 p.m., Anthropic said login success rates had stabilized and that work was continuing to fully resolve the issue. The company did not provide an estimated time for full recovery but said it would issue further updates as remediation efforts continued.

Newsweek has reached out to Anthropic via email on Wednesday afternoon for comment.
