How did you find this url? I would like to get the community edition ISO url, but can only find the RC dated 4/27/2015, when searching download.microsoft.com.
Got it from VisualStudio.com, there is an option at the bottom in the Downloads page to get the ISO which is the same as the one in MSDN (same SHA1 values listed) but has different file names.
Here's English Community: http://download.microsoft.com/download/0/B/C/0BC321A4-013F-4...
