The same thing happened to me. I blocked those URLs and my Wii still updated. I really hope they didn't fix the ppc exploit
Well that's very strange, this are the all IPs I blocked, my Wii U can't update, I have tryied and stills saying that is a server problem:
nus.cdn.wup.shop.nintendo.net
nus.wup.shop.nintendo.net
nus.cdn.shop.wii.com
nus.c.shop.nintendowifi.net
These have worked for me, and they never fail.
