I have used ElasticHosts for a year or so. Their service works very well and are easy to use.

One of the best parts is that ElasticHosts is very flexible, you can scale cpu, ram, disk as you want independent as your system grows. At GoGrid you have to choose between predefined packets.

Another good part is that you can transfer an existing server to ElasticHosts system and let it run there and move it away if you wont for some reason, so you aren't locked to them which feels good.

Another thing you should consider is the price difference, GoGrid is much more expensive.

Thanks for the information.
