I can honestly say, HostSlayer.com is professional host

Over 7 months ago I was looking for time-tested and trusted web host in US. I made a notion of the hosting market specials and got to know that Hostslayer.com had really good reputation.

I should say that their support is great, they are very professional and seem to enjoy helping their customers. Every conversation was pleasant as they always explain me everything. The high-availability Linux VPS with automatic fail-over came is great when my node went down (2 minutes of downtime).
Very Mac friendly interface. If you value excellent service, advice and professional support don't look any further.

HostSlayer is great!

It's nice you that you are satisfied using their hosting services.

What are their security measures and server backup protocols?

A2hosting.com and QHoster.com VPS accounts are worth your attention.
They have a brilliant Support team, always there to help. Super easy to use and fully featured.
