I have high-speed internet, can I host my own site or someone else's?

It is possible, but not recommended. Our servers are colocated in professional data centers with multiple internet connection sources, power generators, humidity control, etc. These conditions cannot typically be ensured on equipment kept outside data centers. In addition to these aspects, the technical knowledge required for installing, configuring, updating, and securing the necessary applications for running the services related to a website must also be considered. Of course, if the site is not an important one and is a test site, the option of self-hosting may also be considered.
