Anthropic SLA: What You Need to Know
Service Level Agreements (SLAs) define the minimum uptime a provider guarantees. Common tiers include 99.9% (the “three nines”), 99.95%, 99.99% (“four nines”), and 99.999% (“five nines”). Each additional nine dramatically reduces the allowable downtime — from about 43 minutes per month at 99.9% to just 26 seconds at 99.999%.
Based on DevHelm's continuous monitoring, Anthropic currently shows a 30-day measured uptime of 99.87%.
Impact on Your Application
At 99.87% uptime, you can expect approximately 11h 21m of cumulative downtime per year from Anthropic alone. If your application depends on additional services, their independent failure probabilities compound — making dependency monitoring essential for maintaining your own SLA commitments.
Monitoring Methodology
DevHelm tracks Anthropic's official status page continuously and aggregates component-level status data into uptime percentages. Data is refreshed every 60 seconds. Uptime is calculated as the percentage of time all components report operational status.
