Best Served w Cold Steel: "A system error occurred during event movement." -- 48 hrs+

UPDATE: Finally got through this main quest scenario after 48 hours.

Type of Issue/Feedback: While accessing the main scenario quest "Best Served with Cold Steel", Stormblood fails to load the solo battle instance, displays the message "A system error occurred during event movement.", and returns my avatar back to the Fringes

Every time I attempt this main quest instance, Stormblood either presents the error "A system error occurred during event movement." Other times, it kicks me off entirely! The same occurs sometimes when accessing DF, PotD, and other solo quest instances!!! :( :( :( There are multiple ways to alleviate server congestion. By not using the proven modern methods, it's quite unfair to your paying customers to permit early release and then for them to be unable to proceed through the main quests to the 1st dungeon!!! :( :( :(

If you are not already using a cloud service provider, you could reduce the risk to your company and investors! Switching to a cloud service provider would alleviate your total lifecycle and operational/maintenance costs by switching to a cloud service provider that can spin up and spin down instances as needed based on the congestion introduced by your users.

I know you are working on this, but please get this error or congestion issues fixed prior to the full launch on Tuesday. Please do everything you can to help out your software users!
