Placeholder images

Looks like placeholder images source is down ( from yesterday. Is it temporary or i need to replace all placeholders images by hand on new ones? Thank You!

The placeholder images are only for mocking up pages and should not be used on live sites, so while their service is down it should not affect your live, published work, just anything you’re mocking up. That being said, you can turn off the placeholder feature and just use the blue placeholder image that is the default for the stack.

i understand it, but default image don’t have dimensions settings, this was very handy. Anyway, waiting when placeholders goes online.
Thank You!
