I've been with Scala Hosting for over ten years now and as hosting companies go, they're at the top of the pile.
Support is fantastic and most importantly, fast. No waiting in queues for a representative, and support tickets are answered quickly and efficiently.
I've tried other services (TSOHost, WPEngine, Fasthost, Bluehost, GoDaddy, Hosting.co.uk) in the past, but Scala stand head and shoulders above them all.
I wouldn't hesitate in recommending Scala Hosting to anyone looking for a hosting solution. They're one of a kind.
