We know SW is messed up. We know it has something to do with the festival. We know it's not just going to fix itself without at least a maint. happening. We know there's a possibility of losing items or doing a "rollback" on your toon due to SW being messed up.
So just STOP TRYING TO GET IN until we hear back that something has been changed. Yes it may take a few days or (much) longer but I for one would wait for a fix then risk losing items or "rolling back" my toon.
The random rollbacks do not appear to have anything to do with siege war. They appear to be a separate bug introduced along side the fire festival. People are being rolled back at random times during the day to random points between 1 hour and 3 days back.
There's another thread concerning that topic as well. Perhaps you should go tell them to stop QQ'ing too, seeing as how incredibly constructive such remarks are.
