OK first off u need a mage. Get him to the UD / baron side of strath, next get your character close to the instance portal ( but dont zone in). After you have done this blink through the portal (it wont zone u in). After that u are free to move forward and u will see a gate in which u click on to open, do this. After that you can jump off and u will have a pretty big drop. Unfortunatly slow fall doesnt stop you from dieing =(. But once you are dead you can see mountains in the background which is supposedly the outland.
Now i have done this all on the test server (U.S.), but i figure if i can get a warlock to SS me i think i can rez there and continue exploring. If there is anyone willing to help me out here plz post. I am on test server

well i while doing this i also found out that you can go into strathholme turn around and blink through the instance that way. Now there is also a little jump after you blink through the instance here too. However slowfall will stop you from dieing here. I am gonna explore around this part and see whats over here then i will post what was there.
