Hello Graham,
I too, was unable to load the "natice" page however we do offer a couple of options that may meet your needs. Take a look at
http://www.ncdc.noaa.gov/snow-and-ice/recent.php
or
http://www.ncdc.noaa.gov/sotc/snow
They may meet your needs. I have also copied our Climate Monitoring Branch in this response. They can address the issues with the natice page.
Regards,
William
