Frontend memory upgrade on Sunday

I'll be upgrading the second frontend web server from 4 GB to 8 GB of RAM tomorrow. I'll do the installation some time during Sunday afternoon Finnish local time (that'll be Sunday morning in the US). I'll move it's IP address to the primary frontend server for the duration of the upgrade, so the service should be available all the time (unless something unexpected happens).

The upgrade should speed up the second frontend a bit (not that it would really have been slow before), and make it do the job for another year or so. It's been a gig or two on the swap before, but there hasn't been significant swap I/O happening normally, so it hasn't really been a problem. This is just a proactive upgrade to keep it performing as well as before, with the increased usage.
