I believe two addresses are published so that browsers round-robin DNS support will failover to the second machine in the case of a webapp FE server failure. Significantly speeding up SSL would be a worthwhile reason for moving to another scheme, but you would probably want to do something to replace the failover mechanism that you are removing. I think a typical solution is to use a virtual IP with some kind of heartbeat to let the second frontend takeover if the other one dies. The downside of something like this is that you are no longer running active-active on the front ends (I think?). Speeding up SSL is a very worthwhile effort and it's awesome that this is being investigated. -- Elliot Murphy | https://launchpad.net/~statik/ _______________________________________________ Mailing list: https://launchpad.net/~launchpad-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~launchpad-dev More help : https://help.launchpad.net/ListHelp
