OK, my Toys R Us games just arrived today, so I went to register them on Nintendo.com... the last time I went there to register a game was when I got Mario Kart DS... and it took three visits to accomplish it, first two times they were down.
So I go there: guess what, down again. Seems like lately the site is at best a 50-50 prospect.
I don't know who's responsible for NOA's server, but they're really doing a miserable job. What SHOULD be a focal point for Nintendo's online marketing efforts is unresponsive, and that's only when you're lucky... usually it's just flat out down.
A site like that's getting lots of traffic, I'm sure... and I think the past year has shown us that whatever that backend software they're using is, it's not up to the job. I'd suggest they lure their web programmers onto a leaky boat and aim it towards the setting sun... I'm sick of having registering my games become a nightmare chore.
