Very good server hosting! Have 3 servers with them with very good support and amazing performance. I will be purchasing more servers next month!
I have had a great experience with TheMinecraftHosting. No lag issues or crashes. The server I owned (1gb) run perfectly with 10+ people and 30 or so plugins.
I have a 12GB with TheMinecraftHosting with 40 Plugins and 3 worlds and it's running very smooth. I recommend this minecraft server hosting for a network or a single server.
I recommend TheMinecraft for the performance & pricing that they have. I got a 4GB server for only $8 and had a very good time playing.
