I'm surprised IGN is bothering to get the old vault back up.
I think the indications were there all along that IGN was trying to update, repair, and migrate the Old Vault as part of a larger site maintenance operation. From what I've been able to gather the IT staff botched the job on some of them, and have been slowly trying to clean up the resulting mess since. My tweets at the IGN execs were based on the assumption that they never wanted to shut down the Vault, and that a little periodic prodding would help them remember to keep it on the list of botched migrations to eventually resolve.
