I have friends who work at a well-known domestic IDC... For some reasons, I happen to know some operational details (I won't disclose the details).
I can only say that the sources definitely won't be limited to Singapore alone. The A100 chips are not in short supply in China. People are still stockpiling them, grabbing as many as they can. Not just the A100, but also other NVIDIA chips that can be used for computing power, such as the H100 and the 4090, are being hoarded. Some people are even hacking the hardware to modify the chips, for example, expanding the memory of the 4090 to 48 GB. In mainland China, chips like the 2090, 3090, and 4090 have all been modified. If you really have the goods, you can just mark up the price and conduct a cash transaction.
The U.S. government is also aware of this situation, which is why the U.S. Department of Commerce has imposed a series of restrictions and created three different tiers for selling these chips.
Regardless of whether there is DeepSeek or not, China's construction of its computing power infrastructure will not be halted for a single step. The amount of funding is actually staggering (many state-owned enterprises that don't even understand much about this field are building computing power data centers, choosing locations based on where the electricity is cheaper, and there are specific targets that need to be met—only areas with electricity prices below a certain level are eligible for investment in construction; I won't go into the specific targets). Right now, it's not the construction of computing power that's lacking, but rather the development of AI applications that can truly generate revenue.
