Amazon DynamoDB SLA
AWS · Databases · promises up to 99.999% · SLA of May 14, 2025 · checked 23h ago
3 major outages in the last 365 days, each in one region (me-south-1, me-central-1 and us-east-1).
Worst region me-central-1: 72 h counted, 99.178% observed against the 99.99% Standard SLA, which applies per region. 2 of 12 months fell below it (credits are claimed per month). The 99.999% Global Tables SLA tier assumes failover to another region, so a one-region outage is not held against it. 2 incidents ran past 72 hours; each counts for 72 hours at most (see the method).
Last 90 days: no major outage.
