Hardware is a bit of a stretch in regards to our official regions, because they are now within the cloud; That magical thing slowly taking over the entire internet. The reason for the move was the trouble we have been seeing with Welcome specifically. We have been unable to pinpoint what exactly is wrong with the region, but with it being moved onto a fresh new machine we are hopeful the problems are solved. We will continue to monitor it and feel free to let us know if you experience any issues. We have also quadrupled the size of the Sandbox region giving you more space to build.
