No doubt we've still got work to do, but the important thing is that things are way better now. No database desyncs, no maintenance windows, just a few times where we've taken the pages down for a few minutes to perform code updates. Happily and thankfully a week after I wrote my 2,600 word End of Year review/essay we managed to stabilize our new server setup and run through some quick but efficient code updates that have enabled us to run the sites almost down-time free over the past week.
