Some websites are inaccessible from target countries due to blocking. The service now automatically selects a working channel for each request to the upstream site and, if unsuccessful, retries the request through another channel transparently to the visitor.
In parallel, a robots.txt transformer has been added: the service automatically checks which sitemap files actually exist on the site and adds only working links to robots.txt. Tilda-specific paths (/tilda/*, forms, participant pages) are automatically closed from indexing.
