According to monitoring by 1M AI News, Anthropic’s official status page shows that 3 out of 5 product lines of Claude are currently in a “Major Outage” status: claude.ai, Claude API, and Claude Code; platform.claude.com and Claude for Government are functioning normally. As of the time of writing, there are two unresolved active incidents: an elevated error rate for Opus 4.6 (under investigation since March 27 at 14:59 Beijing time) and a cowork connection reset error (ongoing since March 25, with the official recommendation to restart the Claude Desktop app as a temporary workaround).
Status page records indicate that within the 15 days from March 13 to 27, Claude experienced approximately 25 independent failure incidents, with no failure reports on March 14, 15, 20, and 24. Among these, the elevated error rate incidents related to Opus 4.6 occurred most frequently, with at least one incident almost every day from March 17 to 27. Several dates saw multiple concurrent failures, with March 18 recording 4 incidents in a single day. Failure types included increased model error rates, frontend errors on claude.ai, login system outages, MCP call failures, and delayed response completions. The 90-day uptime rates are 99.03% for claude.ai, 99.11% for Claude API, and 99.35% for Claude Code.
Combined with the peak hour limit adjustments disclosed by Anthropic on the same day, the Claude service is facing dual pressure from increased demand and capacity.
