After trying to find the best, most stable servers, I was repeatedly told to try HFBservers.com. I paid an extra $15 for their "managed database/bliss support", thinking they would easily fix any problems I had.
I was completely wrong. I had to repeatedly ask them to fix the same problem, and was given no concrete answer as to what was wrong or what they could do about it. This went on for over a week. When I finally asked for a refund, stating that their product had never worked as intended, they completely refused to give me one, not even a partial.
They did nothing when I asked them to increase vehicle spawns (although they said they did, I couldn't tell any difference). Other servers have 300 - 500 vehicles. Mine had less than 40, and they couldn't (or wouldn't) raise it over this number. If you want a server with 300 or 500 vehicles, they will *not* be doing that for you, and they don't have any way to automate that. They don't bother to put that in their advertising though.
I had to contact them numerous times over the week I was their customer. They would commonly respond with auto-messages *warning me that if I responded again before they did, they would drop my issues to a lower priority*. So if I found new information about the problem? Too bad, shut up, you can talk again when we tell you that you can. What nerve. What gall.
I took screenshots of all of this. You can see them here: http://imgur.com/a/pifzj
Give them money at your own risk. I will never use them as a host again. Maybe, *maybe*, if they did a big announcement saying they'd fired their customer support team and hired a real one. Till then, this host has excellent hardware if you are a do-it-yourselfer. If you don't know databases inside and out, AVOID THIS HOST.
A shame too, because I haven't heard of any that come higher recommended, or with better hardware.
If anyone out there knows of a *good* host, let me know, I'd like to find one for Dayz Standalone.
