Anyone using parity for EXP is now on the wrong chain. It would be super nice if people paid attention.
Anyone mining right now, move your miners to http://pool.expanse.tech until your pool confirms they have updated. We notified everyone a month ago and we have noticed there are a few pools still mining the wrong chain. Stragglers are to be expected.
For everyone else mining at pool.expanse.tech, youll get extra exp 
We are migrating to right chain:

Also I've noticed dwarfpool (the biggest one) is on wrong chain.
