Notes — DataStax Astra DB (now part of IBM since May 2025) offers tiered uptime SLAs: 99.9% for Standard and 99.99% for Enterprise plans. Production databases use 3-AZ replication; non-production nodes are explicitly excluded. Credit tier details and claim deadline require direct review of the SLA document.
