Maybe Glados and the CMB made trade some tecnology to them to keep Aperture Science safe, maybe that's how she know about the CMB and she say it in the end of Portal 1.
But GLaDOS kept them out so maybe this is aperture from another universe where instead of testing the humans that atlas and P-Body found she decided to create new stuff and rename aperture.
