The downtime we just had was caused by performance issues. We're working together to see if we can coexist with me not burning the server out and them not cutting me.
When the site is down, updates will be posted over on the Google+ page (https://plus.google.com/107490559295938541532
) and/or IRC (#idolmaster@Rizon). I can answer directly on IRC (provided I'm not asleep).
