It seems like that was their attempt to "shutdown" the site. It's a pretty effective way too... The easiest way to stop the stampede was to drop off the net completely. By tweaking their dns, they were able to give themelves enough room to breathe. Then they could slowly start to bring people back. That's just a guess. But from their post, it seems reasonable.
