Can't download the ZIP file of CWM Recovery from its official site, why? I recently found an old phone (Samsung Galaxy S2) and wanted to download the fitting ClockworkMod Recovery.

Well, when searching for the .zip files on http://clockworkmod.com, I found out that something changed.

What happened to CWM? Why aren't the .zip files not accessible anymore through the browser, and how can I get them anyway?
Discontinued since 6.0.5.1.

There should still be (many) copies scattered around the web, including PhilZ ones, but it's still suggested to switch to TWRP as it's actively maintained, especially if you want to flash KitKat and above.
