I'm John, I live in East London. My main website is m0ukd.com. I have been using Linux and mainly Debian for about 10 years, although i'm no expert! I used to have a 1U rack server in Redbus, London (Sovereign House) which was mainly a game server, amongst other things. I still own the server, although it has not been switched on for many years! This was back in the days before things like VPS and hosting your own dedicated server in a datacentre was quite expensive. These days, you can rent a VPS very cheap, although you do get what you pay for so its worth doing your research first. I have two in Telehouse East (London). One which streams our shoutcast server and the other hosting a few of my own websites, such as m0ukd.com.
About the Pi
There are two things which make it worthwhile using a Raspberry PI as a home server. One is that the Raspberry Pi's are actually quite powerful little machines considering the size and cost. They use a tiny amount of power, and are silent, so 24/7 operation is not a problem. Also, a good home internet connection these days is more than capable of hosting a few things, not that my Pi is too busy!
I originally had the Raspberry Pi B+. When the Raspberry Pi 2 model B came out, I upgraded to that and set up the B+ as a home server (Feb 2015).
Now the Raspberry Pi 3 is here, I changed this server to my Raspberry Pi 2 and sold the B+. Below is a photo of the current board in use.
About the network
I have a 76Mb↑ 19.5Mb↓ PlusNet 'Unlimited Fibre Extra' connection with a static IP. The Raspberry Pi is connected to my router via the 100Mbps ethernet port and has the LAN ip 10.10.10.10
