I signed up 4 domains with ace-host.net and I was happy with them for a few weeks (everything worked fine except the back up restore function on one server).
Then suddenly one site goes down and I get an e-mail saying that their server had been hacked and all my files are lost, but that they have salvaged the SQL databases. I had a back up on another server, so I restored (manually via ftp because the automatic function did not work) my site. However, I don't know what they did to the database, but it never worked with the corresponding scripts again. Their customer support consisted of apologies for the security failure - about 12 apologies, but no technical help. Apparently the back ups they supposedly maintain are kept on the respective server and hence are vulnerable under the same hacker attack (their words).
I had just decided to move that domain to a different host when my other site went down. Now, the first was a new business and really a few days here or there aren't a big deal. But the second one is my main business and even a few hours downtime are a big deal.
I opened a support ticket to enquire what the problem was, assuming this server got hacked too. Some 36 hours (and 3 reminders) later I am told that my site was deleted because it used more than 23% of CPU. The only thing I run that is a bit CPU heavy is a UBB forum and no host has ever had a problem with this (I've been with a few over the last 8 years).
After a further 4 requests I am told that my files will be made available to me but my account will not be reactivated. Mind you I paid them for a full years hosting on all my domains, so at least now we know how they make their money - they scammed me by 9 months.
The promise to send my files was 3 days and many requests ago. They simply close the support ticket without response.
Not getting my files is not a disaster. I have a back up from a few weeks ago, but this puts a serious dent in the dynamic part of the site such as the forums.
My advice is to stay FAR FAR away from them. If their shocking tech support and customer service isn't enough to put you off then consider their poor server security. Kinda funny cos they are the only host i have ever been with that displays the "Hacker Safe" logo on their homepage, while being the only one I know that ever got kernel hacked.
My experience with ace-host.net has been as poor as can be, but as an experienced (yet unskilled) webmaster I am in a position where the damage is limited by foresight. I would hate for others to get into this frustrating situation though.
At this point I am still waiting for my back up files, but i doubt I will ever receive them (the support ticket just got closed again). I am glad they did this after 3 months rather than 6 months as this means I can do a charge back from my credit card on all 4 domains. I'd like to see them try to sue me in Australia
So yeah folks, stay away from ace-host.net.
If anyone needs more info or wants proof I am happy to provide it.
