I was pulling my hair out trying to download atom.io for Windows directly from the site. I kept getting a “This site can’t be reached” error after about 30 seconds. The download apparently comes from http://download-web-shield.com. I thought to myself, “hmmm… perhaps it is because of my ad-blocker… but a free and open-source text editor wouldn’t be so brash as to disallow downloads for users with ad-blocker…” but it was true. I opened a new browser window in stealth mode (no ad-blocker), et voilá! I could download.
Just in case anyone else was having this problem. I couldn’t find an answer anywhere, so now you know. PS atom.io team : maybe you could re-think using download-web-shield.com as your download provider?
