Large images

I'm trying to upload some relatively large images, but it never finishes uploading. "You tried to access the address http://miezaru.donmai.us/post/create, which is currently unavailable"

I was wondering is there a resolution limit? Or is my connection just shitty at the moment?

First image was 5400x2550 and the second image is 2448x3512

Edit: it works now, I forgot I was torrenting...
