I wonder if it's the living remains of GLaDOS on the Borealis if the events of Portal take place before the Black Mesa incident.
And I'm sure it's before the Black Mesa incident as the Combine REALLY wants instantaneous and energy efficient portal technology on the same plane of existence instead of portaling between different universes. Otherwise the Aperture campus would already have been overrun by the Combine as they aren't really concerned about casualties at least from the Transhuman wing and wouldn't let a little nerve gas stop them.
