Where to find download Sierra OS?

My MacBook Pro crashed. While trying everything (Time Machine, re-install, etcetera) I am hindered by the fact that an install of Sierra OS seems unavailable. It's not in the App Store, and when trying an automated re-install through the recovery screen there also is a message that the OS is temporarily unavailable.

Where can I find a download of Sierra OS, to place on a stick to use as boot?

Thanks!

Boot Recovery Mode using one of the other macOS Recovery key combinations described in About macOS Recovery - Apple Support.

From there you can choose to restore your Mac from a Time Machine backup. To restore a Sierra system from your Time Machine backup, read How to use Time Machine to back up or restore your Mac - Apple Support. You will be following the instructions under "Restore everything from a Time Machine backup."

Sierra is no longer available to download.

You can try asking for a copy of Sierra at an Apple Store, but you may need a very good reason to get it.
