Redirect Still Ocurring

Odd Issue: I have a page that was no longer needed, deleted, 301 redirect setup. A few months later someone requested the page go back into service. I pulled the page from a previous backup, reinstated, all good. The redirect, however, still occurs, despite being removed from .htaccess, cache flushed, etc. Where else would a redirect still be in place? Database? Anyone else experience this?
