Areaportals are used by developers to divide the levels loading areas, typically behind doors. So when you pass through a door and then walk, say, 500 yards away from it, the game 'deletes' what was behind the door, leading to either seeing a skybox or, because the Library has no skybox, a blue wall, until you trigger the game to load that area again.This person has had a similar experience.
If you want to experience the areaportal phenomenon for yourself, go up a few floors in The Library, look down into the central column (the one with the Index suspended in the beam) and look down to those huge doors that Spark opens for you, zoom in and you should see a blue screen. I'll try and get pictures soon.
