According to the rules of the previous blogpost, the 1.9 temp server is live now. I chose a biome close to the water since 1.9 has actually working boats. I did not have the time unfortunately to check the world in a larger radius, so I hope the ocean stretches a bit.
I built a mock-portal around the are where the new spawn should be. Please use that small island to build a new spawn without filling in land on the water to the mainland. A bridge would be much better.
