I run a smallish web server with a raspberry pi - an independent, separate server for the website because I don't want it it to keep going offline when I'm playing around with my main machine. I also run an internet-facing file server and ssh server for my private usage. I had some problems earlier with relying on DropBox, so I have 'rolled my own' since 2012. The only thing I've ever noticed the ISP blocking is an email server.
