We installed a load balancer late last night/early this morning. This will make it really easy for us to scale. Granted, we’ve not had any problems with scale so far (even with significant load yesterday, our CPUs stayed nice and cool at 99% idle) but we want to grow and grow. There were a few hiccups (a few blank pages served, and the wrong ssl cert) in the midst of the installation, for which we do apologize. Things appear to be peachy now – but of course please let us know if you ever have any problems.
