prod10 is a server in London running Ubuntu 14.04 (Trusty).


Orain uses HAProxy (High Availability Proxy) to load balance web requests to all domains managed by the Orain DNS. Currently we run a single HAProxy instance on prod10 which distributes requests to the least connected server serving MediaWiki.

HAProxy is also used to terminate SSL requests between MediaWiki servers and the load balancer. As a result, this means all requests to Orain-DNS-managed domains are encrypted when they communicate with prod10 but it de-encrypts them via the Private IP of the MediaWiki servers and then re-encrypts the response.
