Anthropic posts back-to-back major incidents on the Claude API (api.anthropic.com)

Anthropic's status page added two incidents with impact "major", both naming the component "Claude API (api.anthropic.com)" alongside "Claude Code", "Claude Cowork" and "claude.ai": "Elevated errors for Claude Opus 5.5" and "Elevated errors for Claude Fable 5 and Claude Fable 5.1". Both now show status "resolved". Repeated API-surface errors across flagship models read as a capacity-strain signal worth watching against demand; the status page reflects what the vendor chose to post, not an SLA.
