July 2025 infrastructure work focused on reliability, security, and correct routing for Open Food Facts deployments. Key deliveries include automated snapshot health checks via sanoid_check with its own timer, decoupled from sanoid and enabled on OVH1; an Nginx reverse proxy setup for the recipe-estimator service on .net and .org domains with SSL termination, logging, and HTTP-to-HTTPS redirects; fixes to ensure production URLs serve content from the correct environment (proxy_pass corrected to 10.1.0.201); and a server_name typo correction for Folksonomy to route requests properly to the API. These changes improve uptime, routing accuracy, and security posture, while simplifying maintenance and monitoring.
