This is a sanity check.
In the past 24 hours, has anyone uploaded a 3MF file and verified the destination of the download link? I have all .cn domains blocked on my network to prevent redirection to Chinese-hosted domains. This is for cyber security reasons as one will see below why this is important.
Until yesterday, all uploaded files were hosted on Amazon’s U.S. servers. Now I’m seeing this message:
Note: My network is blocking this.
Here it is in another browser and what’s also disturbing is it appears to be randomizing the address based on either browser session or login. That in and of itself is puzzling. There is no value to randomizing the link unless that’s intended for use as personally identifiable data.
Here’s a post where I uploaded a 3MF file. The original poster also uploaded one. Both links, including mine posted just 6 hours ago, now resolve to a Chinese domain:

Here’s the actual file link:

Here’s is what one sees when one hovers over it. It appears to be a perfectly normal link until one clicks on it.
Clicking it silently redirects to:
https://or-cloud-forum-prod.s3.us-west-2.amazonaws.com.cn/original/3X/7/5/757df8589fb89703824ba22293fb0d861c068019.3mf
This is disturbing.
For those unfamiliar with why this is an issue or who haven’t following the TikTok issue, the PRC has the legal authority to compel all Chinese companies to share and or surveil anyone interacting with their platform. Consider that some folks may not be as cyber-aware. With AI, it’s now possible for LLM to scan through models and analyze what the design intent is. That’s no danger if you’re just printing a key ring but what if you have an idea for a product? Do you trust your data in the hands of a site that the Chinese government at any time without disclosure can seize?
