Apr 1, 2025April 2025 monthly summary focusing on stability and reliability improvements. The month was driven by incident recovery for waffle-world, restoring service availability by reverting a configuration change that had set the siksha-spring-server replicas to 0. The replicas were restored to 1 and the siksha-spring-server came back online, minimizing downtime and preserving customer access. No new user-facing features were delivered this month; the emphasis was on incident response, rollback safety, and uptime guarantees. This aligns with business priorities of SLA adherence and user trust.
