I had a lot of my hosting stuff on a shared server from TextDrive/Joyent. Unfortunately (or maybe not) they stopped their shared hosting and I needed to move to a new hoster.
I already heard about Linode and already had a 512MB instance for running the addonsdetector definitions download site. However, I now needed to setup mail servers and all the other websites I had.
I must say, that Linode works great, but above all, it’s their great library with tutorials on every subject you need, that makes Linode great! I now have succesfully setup a quite secure setup, with mail and websites.
I learned a lot during this process, and if you are a bit of a linux guy, really consider it for your hosting!!
