Yep, also been happening to me. Literally saw someone’s body floating down there the second time I was ported there instead. (I assume they were AFK thinking they would be ported to SW like normal.)
Really odd bug since it wasn’t like this yesterday.
Tried to Mage teleport from Dornogal to Stormwind, ended up stuck in the air (falling animation but not actually falling) above the ocean.
Edit: Closed WoW and logged back in to see if I’d fall, and now most of the ocean won’t even render. Still not falling.
This happened to me this morning. I’ve taken the portal twice today and once I ended up in the expected location and the other time I ended up in the ocean off the coast of badlands. One of my horde alts used the org portal this morning and it worked as expected.
Went to confirm, took portal to Stormwind from CoT and indeed landed in Badlands ocean. Maybe some numbers got transposed when setting coordinates?
+10 same here.
happened to me twice now- pretty funny actually
haha, I thought I was the only one…
Yep, same thing has happened to me 3 times today on my main, took SW portal at Caverns of Time, loading screen lags and I end up in the ocean. last time i apparently started taking fatigue damage while still on loading screen and couldn’t get back to my body so I had to take Rez Sickness and repair all my gear 
I just made a portal rather than a teleport from Dornogal to Stormwind and it worked fine.
I then went to Tanaris in the event area, made a similar portal to Stormwind. It was extremely slow and yes, I arrived on my birdy off the coast of Badlands.
So it looks like the Event area is definately messing up teleporting spells. Good to know that, yet again, they cannot seem to patch the game without breaking something.
Had same issue with Cavern of Time portal to Stormwind and was dropped off in the Forbidding Sea.
Was curious about mage portal and whatever you do, do not use a Mage portal to Stormwind while in Dun Morogh. My Mage is stuck falling. Same thing with the Death Knight’s Death Gate in Dun Morogh. That sent my Death Knights falling to their death.
Same. Just happened to me for the second time in a row, porting back to Stormwind.
This just happened to me. Dozens of players were dropping like flies out of the sky and into the water.
Get video of the players falling from the sky!
psure discord has a video record feature in case you need one.
We need it for a good video editor to make us a “remember this” video montage for next years anniversary party. 
Took the Stormwind portal from anniversary location and ended up in the middle of the ocean (fatigue zone). This happened to my guildie earlier tonight as well. A random mage was there as well and was very nice and offered me a normal mage portal back to Stormwind when we got to shore. However, when we took THAT portal we ended up in the middle of Tristal Glades. Please fix this ASAP.
When the portal loads slowly and you are half dead by the time you realize you are in Badlands fatigue water. Fun.
This just happened to me as well. Then a mage that was also sent to the badlands ocean of doom made us a normal mage portal once we got to land. However, we ended up in Tristfal Glades falling to our deaths. Good times Blizz.
just had the same thing happen to me, followed by lots of people falling from the sky. Actually pretty funny but annoying.
Me too. Middle of the ocean near the Badlands.
Myself and several other people just had it happen.
Just happened to me. Caverns of Time portal to Stormwind dropped me over the ocean off the east coast of the Eastern Kingdoms.
Edit to include I noticed several others with me, all rushing to beat the fatigue timer and get back to land
