With the release of Home on PSN. Everything has not been that smooth, at first it was delayed. Only for a few hours. After that there has been a load of reports stateing that home users have been getting connection problems.
Today Sony has addressed the problem stateing
: We are aware that some people may be experiencing difficulty in accessing the PlayStation Home beta at present. This is due to overwhelming demand for the service as people access Home for the very first time since it became Open Beta and appeared on the XMB. While we prepare solutions to ease the problem, you may continue to experience difficulties accessing Home. We kindly ask for your patience as we work to meet the incredible demand for this revolutionary service.
So hope fully they will have this issue worked out quickly
