Block account finder

Pick your current Usenet provider and get block accounts on a different backbone — so a missing article on one backbone is filled from another.

No block providers on a different backbone — try another provider.

A block account only adds reliability when it sits on a backbone your main provider does not use. Add it to SABnzbd or NZBGet as a lower-priority backup server: your main account is tried first, and only missing parts fall through to the block, so it lasts for years.
