Not sure if this is the right area, but the current Nether Portal is in a horrible location. It is completely isolated, up very high, and due to the protection around it, there is currently no way to build to safety. Reaching anywhere unprotected without an Elytra or flying without falling to your death or into lava is currently impossible.
I've created and protected a stairway/bridge down off the main portal island. Looks like this is just a bad luck result of generation as each world is randomly generated each month. Either way you should be able to access the rest of the nether now.
We'll have a new one done this month on the 26th. Only 2-3 days to go. Unless it's late for some weird "andrew" reason.
