Oct 1, 2025Month 2025-10 — Focused on robustness and scalability of bulk domain contact removals in google/nomulus. Delivered resilience and rate-limiting improvements to RemoveAllDomainContactsAction, reducing risk of bulk-operation failures and safeguarding system load during large-scale removals. Implemented per-domain failure handling that logs errors and continues processing, and introduced a configurable rate limiter (default 10 QPS) adjustable via query-string to prevent overload. Result: more reliable bulk operations, improved customer experience, and stronger operational safety nets for large-scale domain management tasks.

Aug 1, 2025Month: 2025-08 — Summary of work on google/nomulus focusing on Expiry Access Period (XAP) groundwork and related configurability. Delivered foundational backend support for XAP by adding a new boolean column to support per-TLD expiry controls, with configuration managed via YAML. This enables safe, configurable rollout and experimentation for XAP.

Jul 1, 2025July 2025 monthly summary for google/nomulus: key highlights include two major contributions: accurate metric aggregation for sampled requests/responses and a new feature flag to prohibit contact data during EPP/domain updates under MINIMUM_DATASET_CONTACTS_PROHIBITED. These changes improve metric accuracy for monitoring and reporting, and strengthen data privacy governance across core flows. Additionally, test updates and validation refactors accompany these changes to ensure long-term reliability and safety.

Mar 1, 2025March 2025 monthly summary for google/nomulus: Implemented a critical fix in monthly transaction reporting to correctly handle negative values. By applying floor at the report level, the system preserves valid negative amounts from domain cancellations during the grace period, ensuring accurate ICANN validation reporting and reducing potential compliance risks. The change is tracked under commit 04b30f5c04710a0b323e6de6da9ef95af22a6f26 and enhances overall data integrity and reporting reliability.

Nov 1, 2024November 2024 monthly highlights for google/nomulus: Implemented critical correctness and performance improvements with a focus on business value. Updated UpdateRecurrenceCommand domain transfer handling to permit updates when transfers reach COMPLETED state, accompanied by tests to validate behavior. Corrected a typographical error (Domian -> Domain) to improve clarity and professionalism across the codebase. Enhanced poll message flow performance by downgrading transaction isolation to TRANSACTION_READ_COMMITTED for both request and acknowledgment paths, reducing contention and increasing throughput while preserving idempotency for acknowledgments. Overall, these changes improve transfer reliability, code quality, and messaging scalability across deployments.
