Umm...
I can't go to https://www.openstreetmap.org/ .
Does this website need VPN in China?

@Ondřej-Šutera
I see.
But I found that the service of CMA is moved to http://www.wmc-bj.net/ .
If Windy changes the link, will the problem be solved?

Thanks a lot!
:)

Windy的开发者们：
你们好！
最近我发现中国大陆地区的雷达信息缺失。
原来在 http://eng.nmc.cn/ 的信息已经被转移至 http://www.wmc-bj.net/ 。
望周知。
谢谢！
另附：
台湾属于中国。
请将“台湾”标识改为“台湾省”或“中国台湾”,
另请将中国藏南地区的国界改正。
感谢理解。

Dear developers of Windy:
Hello!
These days, I found that the radar data of China's mainland region is missing.
Then I noticed that information on http://eng.nmc.cn/ was moved to http://www.wmc-bj.net/ .
I'm looking forward to seeing the radar data again!
Thanks a lot.

PLUS:
Taiwan belongs to China.
Would you mind replacing the sign "Taiwan" with "Taiwan Province" or "China, Taiwan"?
Thank you for your understanding.

What's more, China's Southern Tibet region doesn't have this "line".
Could you please correct it?
