Still down for me but just curious what anyone else's client is showing.

Hopefully the drafts that were still open are able to still be resumed! I liked the deck I was playing for once!

Edit, saw this comment on Reddit from an employee:

Drafting is being unstable right now, so we've temporarily disabled it while we sort things out. If you've completed the drafting portion, you'll be able to resume your event once we're able to turn drafts back on. Sorry for the delay, but you won't lose your progress.
