A website is not finished at launch; it goes into operation. This category covers everything that follows: hosting and server choice, loading times and Core Web Vitals, caching and image formats, updates and security questions, backups, and monitoring that notices outages before customers do. We explain which measurements really help day to day, how to narrow down bottlenecks and which maintenance tasks can sensibly be bundled. The organisational side is included as well: responsibilities, access credentials, documentation and dealing with service providers. The goal is a website that runs stably and whose condition is verifiable at any time — instead of problems only becoming visible through an outage. We additionally show which documents belong to clean operations: credential management, an overview of contracts and an incident procedure.
