 ## Using SSL With Cloudflare
 
 Cloudflare offers SSL offloading. You can upload your SSL certificates to Cloudflare to make use of SSL. If you choose to do this, always manually order your SSL certificates so you can use the same certificate on both the Cloudflare servers and the Hypernode.
 
 If you use manual SSL certificates, make sure you monitor when your certificate is about to expire.
 
-You can also use a [Cloudflare Origin CA certificate](../../hypernode-platform/ssl/how-to-use-a-custom-ssl-certificate-on-hypernode.md#use-a-cloudflare-origin-ca-certificate) to encrypt traffic between Cloudflare and your Hypernode.
+You can also use a [Cloudflare Origin CA certificate](../../hypernode-platform/ssl/how-to-use-a-custom-ssl-certificate-on-hypernode.md#use-a-cloudflare-origin-ca-certificate) to encrypt traffic between Cloudflare and your Hypernode using a certificate signed by Cloudflare. This way you can use Cloudflare SSL/TLS mode **Full (Strict)** without having to worry about your certificate expiring.

 Redirecting from HTTP to HTTPS can cause a *Too many redirects* error. This error comes from a cached redirect that is served on both HTTP and HTTPS connection, causing the site to redirect from HTTP to HTTPS.
 
-To redirect all requests to HTTPS when using Cloudflare SSL, you should instead use [a page rule with the Always Use HTTPS action.](https://support.cloudflare.com/hc/en-us/articles/203295200-End-to-end-HTTPS-with-Cloudflare-Part-2-SSL-certificates)

-## Don’t Use Railgun on Hypernodes
-
-Cloudflare provides a service called [Railgun.](https://blog.cloudflare.com/cacheing-the-uncacheable-cloudflares-railgun-73454/) The key to this service is a local proxy daemon that sends all requests from Cloudflare through a tunnel to the proxy instance that does the actual web requests.
-
-Our tests with Railgun on Hypernodes showed a performance gain of just a few milliseconds, making it not a very significant performance optimization when working with Magento.
-
-As we do not support Railgun (yet), we’ve seen some implementations running the Railgun daemon on a separate server. Doing so is not recommended as it will make all HTTP requests from Cloudflare arrive from the same remote IP.
-
-When someone is trying to brute force your server or in case of an attack, our protection mechanisms will block the attacker. When you use Railgun, our mechanisms will not block the remote IP but block the IP of the Railgun daemon instead, blocking all traffic coming from Cloudflare and therefore block all visitors to your shop.
