If you own a PSP and follow this blog, it is likely that you installed the latest Pro CFW on your console, and you might be enjoying the new online functionality that was added recently by Coldbird. (For those who don’t know what I’m talking about, the latest Pro CFW allows you to play online with games that would only allow adhoc mode otherwise. For details on this feature and the free service provided by Coldbird, check this article.).
Sadly, the central server for this service is currently down for a lot of users.
I contacted Coldbird who is aware of the situation. The server itself is fine, but it seems there is a problem with DNS resolution (the server lost its name…). Coldbird tried to solve the problem yesterday, and apparently this solved this issue for some countries in Europe, but as far as I can tell it is still impossible to reach the server from Japan at least. Feel free to report success or failure to connect to the prometheus server (prometheus.uk.to). I will keep you updated if I get more news from Coldbird.
