I just tried the eshop again, still not working. When it couldn't connect to eshop, it caused my wiiu to disconnect from internet completely. Didn't allow me to go on miiverse or use netflix again. It took about ten minutes for it to reconnect, but still no eshop.
Nintendo's servers clearly weren't ready.
