Hi @user8852, it appears to be enabled for two of your zones but is not active. And, since you did not install anything on your server, it won’t be active. I’ll dig internally for clues as to why it’s showing as enabled and post back when I find something.
Edit - Some references to a UI defect that causes railgun to show as active. Chased it down internally and this is known and being tracked. It can be introduced in accounts that have a mix of biz and free zones or zones that were moved from a partner. If it causes any issue (it should not), please let support know.
