Downloading CUDA toolkit and cuDNN is super slow today

I’m trying to download CUDA toolkit and cuDNN to upgrade to 10.2 but downloading speed is super slow (just about 30KB/s) today and it keeps failing to download. Previously I could download CUDA in several hours but today it repeatedly fail to download. I tried in my office and my home and the situation is same. It seems to be not due to my local network since I could connect and download files from other sites. There must be something problem in machines and network. I hope the network or machines get to be normal quickly.
