It seems like Valve is not the only company to suffer from overestimating their servers' ability to handle the Holidays and the influx of people who want free stuff (Steam's servers where hammered when Valve offered Left 4 Dead 2 for free), as Nintendo has had to remove the Pokemon Bank and its companion app, the Poke Transporter, from the Japanese eShop (both of which were offered for free for a limited time).
