Can't download Quartus II 13.1 for Windows.

I see the same thing. Going to:

https://www.intel.com/content/www/us/en/software-kit/711791/intel-quartus-ii-web-edition-design-software-version-13-0sp1-for-windows.html

results in a window like this:

that spins forever (or at least 5min, I gave up).

Windows 10 Firefox or Chrome, same behavior.

The page used to work. Now it doesn't.

Appears to be an Intel website problem that they need to address/fix.
