We've been hearing some reports that certain images aren't being served to some users over the CDN Discourse uses. For example:
Some initial investigation led to finding this image being served over
p-uswd00.kxcdn.com (188.8.131.52) as opposed to some other (working) CDN nodes for others.
I'm reporting this several hours after hearing about the issue, but even if the CDN's cache has been resolved in the interim, it would be good to know if we can avoid CDN cache misses like this if possible. /cc @skearns
