m using Hosting24 to host WordPress sites. They offer all the premium features of the top-end managed sites, but at a fraction of the cost. In the Geek package, you get Varnish caching, Memcache (both of which can be controlled by their own custom plugin) AND Clouflare Railgun support. This combination makes your site blazingly fast.
But what's best is their support. They boast about a 10 minute response time to their tickets, and that's no idle boast. The last four tickets I raised were responded to in an average of 8 minutes, and all of them resolved immediately.
You'll get the most out of Hosting24 with a bit of technical knowledge (it's not fully managed, after all), but you don't have to be a genius, and the support is truly second to none.
I've had several web hosts over the years, and I've been satisfied with all of them, and delighted with most - but so far, Hosting24 surpasses them all.
