I wish them luck. They must be getting a ton of s**t from many people already, but hopefully this maintanance will fix their issues permanently. I kinda like Kraken. Don't know why. Centralized exchanges are soon becoming obsolete anyway.
Sorry for people who hold too much money on exchanges. It must be scary times whenever an exchange goes down for maintanance. Everyone is saying this, but I will repeat too: Keep your own private keys.
