This site runs on WPEngine. I love those folks for dedicated, secure WordPress hosting. I have sites hosted in quite a few different places, and I’ve never had better combination of uptime, speed, security and support. They are quick to communicate when there’s an outage or issue, and quick to respond to support requests, even those that aren’t server issues.
Through January 31st, you can get 15% off their annual plans using coupon code NEWYEARNEWHOST15, which is a great deal. Stop messing with cheap, slow, shared hosting and upgrade to a dedicated WordPress host.
It’s pretty easy to migrate, but if you need help, let me know.
