This planet, and all of it's Zones, are closed. Move along
AHA!!! That is where my problems with startradersrpg.proboards.com/post/176701 came from. It wasn't a matter of 'fly in on a different angle to the planet, hope you end up at a different Zone' as I thought, but 'wait for the Quarantine to go away'. Sigh. sorry for the noise earlier.
