Does anyone have a business subscriber Internet connection? Is it worth it?

I just spoke with my ISP, and for an extra $40/mo I can get a static IP address with 100mbps that I can host my own website on. I have a virtualization server, and I've been thinking about hosting my own hobby-scale website for a while. I haven't had any luck finding rack hosting space that I'd feel comfortable using so I'm thinking about just going rogue, and operating solo. If I had a static IP address with a pipe that would allow me to host then all I'd need to do is stand up a server, register a domain, and point it at my IP address.

Other than the typical security risks, what do I need to worry about? Would the experience be worth it?

teknik.io is a website that provides services like email, [encrypted] file uploads, Git repos, blogs, URL shortening, and more. I've used them for a few years and they're wonderful. It's all open-source and privacy conscious, maybe some Tildes users would like it?

Registration is usually invite-only, but it's open for a few hours.

Thanks @duckoverflow for mentioning this.

Edit: also their privacy policy is short, simple, and easy-to-read if anyone is interested in that. I'd consider it a great example of what a privacy policy should be.
