Everyone don't panic! AU is be coming version 2. Or AU 2.0.
It was put into beta back in October and is now switching over to it. I know this simply because I've been beta testing it as well, as have a handful of others.

I personally like v2 it's faster more reliable when typing upload speeds are faster it needs more than 500mbs for media upload but other than that it's a greater version of an already amazing platform.

The switch is why everyone's lagging/failed to upload/profile/

Just have patience frens!

Love that second-chance edit feature for grammatical errors*
