Actually, now it's broke for me again

Though, I have a strong idea why. Now, if only we can get it fixed
That's a bit vague and unhelpful, now isn't it?
I have found, that when I am working from home (US based IP address), I get this set of broken images (and many others):
However, when Bluelighting from work (Shhh!!111), which routes through European servers (and IPs), I get this set of working images:
Regardless of browsers used, or devices, this behviour seems consistent to me with being tied to IP addresses getting blocked from accessing the image files. We don't have someone adjusting permissions on the server to fix, then break again. It appears to be the IPs I'm coming in from...which makes me strongly believe this is related to our cloudflare defense system. This would echo, IMO, with people who were experiencing site issues when the cloudflare was set even higher during our DDOS attacks. Cloudflare is still on, but at a lower setting, but I think it is the cause.
Can those of you with issues or no-issues, also comment as to your experience when cloudflare was set to a higher defense level (roughly JUN-OCT of last year), as well as roughly where your IP is coming in from (don't give away more info than you wish, just trying to find correlations here). Thanks.
