I have been working with vexxhost since 2013 or so when they hosted my first website using WordPress which got hacked to bits (the client was not happy!).
Since then i've used them many times over different projects - mainly web apps but now moving into more complex systems like IoT gateways etc! They are very professional hosting providers who really take care about their customers needs & wants from day one through support right up until go live/deploy date ensuring all goes smoothly without any issues at handover time.. Highly recommended!! Nothing specific that comes immediately mind though just would be nice if there were some sort off "best practices" guide available regarding running your own server rather than relying 100% upon another vendor's setup process?
