I believe that you should consider choosing stable vps. You may also choose to have cloud hosting since its a better way of avoiding insident of system down, because of grouped servers. And by choosing, you need to consider the money that will be involve and the benefits it will give you. You can refer to all the reviews available, so that you will have more information on the best step you will take to bring your site to the next level

A cloud would be a wise decision since cloud hosting is based on high end networking technology which assure you 100% power/network uptime.
If you are trying to target UK traffic try to go with UK host who have cloud in UK datacenter and hence will provide you UK IP for your website.

To OP,

Could you share your experience with us?

What host have you chosen? How helpful is their support?
