Summary
Anthropic reported that all of its non-government Claude services failed to meet the two nines (99%) uptime threshold during March 2026, marking a significant reliability concern for the company's commercial API offerings. The shortfall suggests infrastructure challenges or increased demand that strained the company's service availability during the month. While the specific cause of the downtime was not detailed in the report, the miss represents a notable departure from typical SLA commitments that many enterprises expect from mission-critical AI services. Government-operated Claude services reportedly maintained separate uptime metrics and were not affected by the same issues.
