What does 99.9% uptime mean for inference?
The post defines three inference reliability tiers by the failure domains each must survive: 99% requires surviving node-level GPU failures like ECC errors and thermal throttling through automated health checks and fast replica replacement within a single data center. 99.9% requires surviving a full data-center failure by deploying weights across two facilities with enough capacity on each side and routing live traffic to both continuously, not a cold standby. 99.99% requires multi-region deployment with AZ redundancy and reserved failover capacity. The authors argue that vague SLA definitions hide which failure domains are covered, and that infrastructure ownership—whether a provider controls its hardware or rents from a hyperscaler—determines how quickly failures are resolved.

The best engineering reads, once a week.
