April 2025 delivered stronger security hygiene, automation, and domain lifecycle cleanup across Puppet and TLS ecosystems. The work focused on adding robust, non-interactive MediaWiki automation, tightening SSL lifecycle handling, and removing stale certificates across DariaWiki and OSFirstTimer domains, while correcting infrastructure node role mappings to improve reliability.

March 2025 infrastructure and security enhancements across miraheze/puppet and miraheze/ssl delivered automation, UX improvements, and security hardening. Key features include Python virtual environment provisioning for MediaWiki deployments, password reset redirect, enhanced SSH key management for Rhinos admin access, IRC RC bot multi-instance support, and SSL provisioning with Cloudflare migration and certificate hygiene. In addition, MultiPurge configuration was removed to simplify maintenance. Overall impact: reduced manual steps, faster, more reliable deployments, improved security posture, and scalable operations.

January 2025 Monthly Summary Key features delivered: - Cloudflare SSL certificate deployment for miraheze/ssl: migrated certificate issuance from Let's Encrypt to Cloudflare, removed the old Let's Encrypt cert, and updated certs.yaml to reflect the CA change. This ensures Cloudflare-issued certificates are used, enhancing security and user trust. - TLS 1.3 enforcement across core infrastructure in miraheze/puppet: standardized TLS 1.3 as the minimum security protocol across icinga, MariaDB, haproxy, nginx, and zookeeper, reducing exposure to older TLS versions and strengthening data in transit. Major bugs fixed: - No distinct major bugs reported in this period. Work focused on security hardening and certificate management rather than defect fixes. Overall impact and accomplishments: - Substantially improved security posture and trust with users through better certificate management and protocol hardening. - Achieved reproducible, auditable changes across two repositories via descriptive commits, enabling easier rollbacks and compliance reviews. - Reduced operational overhead for certificate lifecycle and aligned with security/compliance requirements. Technologies/skills demonstrated: - Cloudflare certificate management and CA changes, certs.yaml configuration, and YAML-based deployment tooling. - TLS 1.3 minimum enforcement across multiple services (icinga, MariaDB, haproxy, nginx, zookeeper). - Cross-repo coordination, traceable commits, and security-focused engineering practices.

December 2024 monthly summary for miraheze/ssl: Focused on strengthening configuration quality controls by enabling YAML key uniqueness validation. Implemented YAML linting improvement: Enforce unique keys with the key-duplicates rule by updating .yamllint.yml. This reduces YAML config errors, improves maintainability, and mitigates deployment risks due to duplicate keys. Change is backed by commit: c34547e8f8cc677a24b8107c81bb683a3c69e841 (Update .yamllint.yml (#813)).

November 2024 monthly summary for miraheze/puppet focusing on bug fixes that stabilize deployment workflows and improve CI reliability. Delivered a targeted MWDeploy bug fix and accompanying test improvements to increase test isolation and reliability, reducing false negatives and deployment risk in beta environments. The changes were reviewed, merged, and integrated into the puppet repository, delivering measurable improvements in deployment safety and feedback speed.
