They simply had the misfortune for their servers to be located at a web host that was affected by the power outages in Los Angeles yesterday.
If my inbox is any indication, it got a lot of folks thinking about what would happen if MySpace suddenly disappeared. If you're only using "free" sites like MySpace or PureVolume or SoundClick to promote your band, you can't control what's going to happen to your potential fans if they only know to look for you on those sites.
Posting free profiles at those sites can be an effective strategy, but you still need your own site as an anchor. For only a few dollars a month, you can sign up with a sitebuilder like Bandzoogle or HostBaby, get your own domain, and know that your main website won't be going anywhere without you knowing about it.
