wp_redirect only works on main site and not on other sites

get_option is a per sub-site function. In other words it gives you only the value of the option in the sub-site.

If you want to have a netwrok wide option you should use get_site_option and update_site_option.

You can also query an option from a specific sub-site by using get_blog_option and passing as parameter to it the main sub-site id, but in my opinion, get_site_option should be preferred.
