After a month trying Contabo, I must say that:
Don't use their servers.
Their storage bandwith policy is good, I will keep continue using it. But no way I'm go back for their server.
It's always down!
I have no idea why.
Their supporter is nice, but did not help.
I'm going to use HostHatch for an experiment.
They have a lot of locations in Asia, like Hongkong, Singapore and Japan (with cheap price).
I'll comeback for more reviews.
