March 2026 monthly summary for miraheze/puppet focused on strengthening secure admin access and tightening Content Security Policy handling in Varnish. Delivered two features with targeted commits: SSH Key Management to enable passwordless admin access by adding RhinosF1's SSH key; and Varnish CSP handling improvements that refine backend hint checks and ensure CSP headers are emitted only when necessary (avoiding CSP on 304 responses).

February 2026 monthly summary for miraheze/puppet: Delivered reliability improvements for core IRC services and implemented travel-related security controls. These changes reduce runtime outages by ensuring services actually run (cvtbot, irclogserverbot, ircrcbot) and prevent unauthorized access by disabling the phone key while traveling. Overall impact: improved uptime, stronger access controls, and a more resilient configuration baseline.

December 2025 monthly summary for miraheze/puppet focused on database performance optimization via targeted MariaDB configuration changes. Implemented and corrected binary-logging disable for the parser-cache database (db201) to lower logging overhead and disk usage, enabling more predictable I/O and better throughput for the parser-cache workload. No major bugs reported this month; at least one corrective patch ensured the binlog-disable logic is consistently applied across db201.

October 2025 monthly summary for miraheze/puppet: Delivered a DNS resolution reliability fix for mattermost1 by updating resolv.conf.erb to include the search domain vps.wtnet. The patch reduces DNS-related connectivity issues and name resolution failures, contributing to improved uptime and user experience in the mattermost1 environment. Implemented a single, focused change in Puppet manifest with a clear commit (577d2cb6a24d41bf0b02727daa586a4fea31b89f), reflecting efficient change management and traceability.

July 2025 highlights for miraheze/puppet focused on credential hygiene and access governance. Delivered SSH Key Management for Rhinos and RhinosF1 to tighten access control, reverted an unintended SSH pause to restore Rhinos access, and updated user privileges by adding Skye to the mediawiki-admins group. These changes improved security posture, ensured auditable change history, and maintained business continuity with minimal downtime.

June 2025 monthly summary for miraheze/puppet: Implemented MediaWiki Admin Access Management to strengthen access governance for the MediaWiki environment. This included provisioning an elevated admin role for a new test user and updating existing admin rights, enabling secure, auditable changes in the test environment. The changes prepare the ground for RBAC expansion and safer admin onboarding across environments.

May 2025 highlights across miraheze/ssl and miraheze/puppet focusing on security hardening, config standardization, and release process alignment. Delivered Cloudflare-backed SSL migration and cleanup, certificate management simplification in Puppet, standardized SSL monitoring, and beta branch alignment for MediaWiki REL1_44. These efforts reduce operational risk, simplify maintenance, and improve consistency across SSL management and release workflows.

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.
