Update (12 PM on 12/29/13): The Nintendo eShop is back on all systems.
The Nintendo eShop has had some rough times over the past few days. We have been reporting on updates as we receive them. The latest comes straight from Nintendo. They wanted to share a bit more of what has caused the problems and their approximate date and time for the fix.
Thank you very much for your patience while we perform maintenance on the Nintendo eShop and Nintendo Network. We sincerely appreciate your ongoing support. We wanted to share some details on what is causing this downtime, and update you on the current outage in service.
The initial outage was primarily caused by a one-time surge in demand over the recent holidays, compounded by the following:
1) An influx of new Nintendo Network accounts being created and accessing the Nintendo eShop.
2) Existing Nintendo 3DS account information being moved to new Nintendo Network accounts.
We are continuing to adjust our network to meet the needs of all our services and applications. To ensure our global audience has an expected level of consistency in service, we took the Nintendo eShop on Nintendo 3DS offline. We expect to have it back online no later than 4 a.m. ET on Dec. 29, but may have to perform more maintenance in the future.
We truly apologize for the inconsistencies in our online services. We are working hard around the clock to fully restore these functions, and will continue to keep you updated on our progress.
