Still not in the same league. Tagging the white house or pentagon would mean breaching a secure perimeter, whereas this was probably just a minor inconvenience to a sysadmin somewhere for a couple of hours. Nobody would have to assure the public that the President's life was never in danger because someone took down the white house's website. Sneak close enough to touch the windows and survive and it's a different story.
