I have refresh pattern for each of the domains separately.
The pattern gave about 7 days of cache for an object until I upgraded
from 3.1 to 3.2.1.

These objects aren't really "risky" because they are static.
And it's funny that you can see all over amazon cloudfront cdn headers
that it is being cached already...
for the first 10 request amazon cdn showed a cache miss and then hits
one after the other.
