I could not possibly describe the issue any better than it is already described here: Images from i.sstatic.net only work for me after being accessed from another IP address [closed]
The question is closed as resolved, but it certainly isn't for me and for many other Stack Exchange users. This is how I see most questions and answers for a year now:
I could visit the same page from my mobile device that uses another ISP and the images would be instantly fixed accessing the page from the first PC, but now my mobile ISP has same issues:

When I try to access the image, I get this:
Using a proxy helps.
Sometimes they start to work, I suspect when another user near me accesses the same page and Cloudflare server serving the region gets unstuck somehow. This just happened with this very post and I can see images on it for some reason. But this might not happen for weeks and some posts remain broken for me.
I actually switched to a completely different ISP and still experience the problem. This probably means that Cloudflare services are just constantly failing for entire regions. I have since encountered many people experiencing same issue.
