I tried to download the SDK (2.9) located at https://developer.amd.com/amd-accelerated-parallel-processing-app-sdk/ for a few hours on two different computers.
It usually starts downloading at 200K/sec, about 3/4 of the way. Then it slows down and finally the browser (firefox, latest) gives a FAILED error.
I tried with or without proxy, from Linux and Windows machines, same results.
Sometimes it starts to download faster, about 1MB/sec, but the same result. It fails a few minutes later.
It has nothing to do with popup, as I already clicked ACCEPT to start the download.
It has nothing to do with my network, as I download hundreds of files from other sites without issues.
I was able to download the SDK eventually, but it should not take 20 tries to download a 100-something-MB file..
