I'm glad you asked this question because I thought it was just me having technical issues! I also can't make it on to Chaos (Spriggan) but a friend was able to do a whole praetorium earlier. I'm so confused. I keep seeing the queue to log in vary from 90ish to 150ish Hope you're able to make it on! I was able to log in to one of the NA data centers, but still not Chaos.
