I noticed some changes a couple of days ago as well.
It stopped displaying the snowflake map on my iPad. Never had a problem with it before that.
It displays the map ok on my PC. However, if I use Internet Explorer as my browser the "back" button does not work. If I click on a snowflake to see a specific cam, when I click "back" to try to go to the map again it jumps to a blank tab in the browser. It works correctly on Google Chrome, but very slowly.
