Quoted from Spaces.msn.com “Please note that your MSN Space's URL will change on June 5, 2006. As part of investments in the improvement of MSN Spaces, it we will be migrating all of the URLs from http://spaces.msn.com/<NAME> to http://<NAME>.spaces.msn.com. (For instance, instead of http://spaces.msn.com/thespacecraft/ you will now see http://thespacecraft.spaces.msn.com.)
On and after June 5th, all viewers and users going to the "old" URL will be automatically redirected to the new URL. In addition, your MSN Messenger/Windows Live Messenger buddies will also be automatically directed to the new URL when they click on your contact card to view your Space. We want to assure you that all of your data and information will remain intact, and we apologize in advance for any inconvenience this may cause”.
