If you want your Web pages to be accessible all the time, the Web server must have a direct Internet connection. Getting your site up and running, not to mention updating and maintaining it, can involve quite a number of tasks. Load files onto the server and prepare them for access. Validate the HTML tagging, verify links, and test for usability. Schedule acquisition of new content.
Nothing is worse than stale information.
Schedule hardware and software maintenance, upgrades, and backups. Enable optional services such as firewall security, user registration, user authentication, or use statistics. Provide hooks to external databases for facilities of electronic funds transfer. Register and promote your site so others can find it. And this task list is by no means exhaustive, but don't let it frighten you.
