I would and do. I have gig fiber which is more than enough for both my home and web service uses. The level of hardware I can bring to bear is far beyond what I could afford in a DC. Sure there are sometimes internet or power problems that you don't usually get in a DC but they are rare and are made up for by me having physical access to my servers when something goes wrong.

Plus it's fun.

I have a VPS subscription, which I use as a reverse proxy. Most of my services are on a headless computer in my bedroom. The two are connected with wireguard. (I also connect some SBC's to the VPS to host some other services)

Works perfectly, haven't had any connection issue or downtime expect when I manually reboot or service the case.

Currently:

22:26:03 up 230 days

If I did, I would put it behind something like Cloudflare. I do host a number of lower-traffic WordPress sites from home (<1k hits month). Oddly enough I actually do have backup power so reliability is pretty good.

I would not host anything bandwidth-heavy.

I avoid it for security reasons. But I have heard using Cloudflare can alleviate some concerns. And it is tempting to host at home because I have significantly more resources and bandwidth than I pay for on my cloud VPS

No, definitely not. I don't want my home network to be in any way accessible to the public. No matter how secure you think your network is.

I do for my personal services.

I'm waiting on the internet to go down one day to see how my personal instance of Lemmy works out offline.
