I wasnt sure where to mention this, so I figured here was best. It seems like the simple itk documentation is down (or changed addresses?).
I tried navigating to some of the google links for specific topics and found a 404 error with ITK banners. I then navigated to a simple itk page that lists compatible filters (https://simpleitk.readthedocs.io/en/latest/Documentation/docs/source/filters.html) and tried to access one (binary closing) and it again shows a 404 error. (https://itk.org/SimpleITKDoxygen/html/Python_2BoarderSegmentation_8py-example.html). I tried a few other random ones and got the same response.
Anyways, just thought I’d share/mention this in case this is not known.
