Uptime is consistently surpassing 90%! Well, I guess it's progress. :)

My comments from a post-embargoed version, from another discussion (https://news.ycombinator.com/item?id=6824061 https://news.ycombinator.com/item?id=6824061): 400 bug fixes ~= 200 new bugs inserted? (Well, at least initially.) Page 5, hardware upgrades: "Deployed 12 large, dedicated servers; upgraded storage unit", with a resulting ">3x Database Throughput" Don't like reading that, although maybe it's not the critical path slowdown now. "upgraded storage unit" sounds like they're using a SAN, NAS, what have you, not the ideal recommended cluster architecture for MarkLogic (the main database, chosen by CMS to the dislike of the contractors). I wonder if they've got enough IOPs.... Ah, reading this: http://online.wsj.com/news/articles/SB10001424052702303332904579228413800602836 http://online.wsj.com/news/articles/SB1000142405270230333290... confirms what we've been hearing about it running on VMs on machines shared with other Medicare services, vs. the dedicated hardware now. System stability is bad at 95.1% exclusive of scheduled maintenance. Per this table https://en.wikipedia.org/wiki/High_availability#Percentage_calculation https://en.wikipedia.org/wiki/High_availability#Percentage_c... that's a bit over 8 hours a week of unplanned downtime. Hmmm, maybe not a total disaster now. And the fix-it czar said his highest priority was (correctly) to stop sending garbage to insurance companies. We'll see ... especially since they evidently haven't started working on the really hard problem of paying the companies....

Interesting to see the monitoring tools in place... New Relic, Mixpanel and Chartbeat. Would like to have seen more detail included from these, seem to be focused on backend. Where's the real user monitoring data or front-end performance via tools like http://www.webpagetest.org/ http://www.webpagetest.org/ or http://speedcurve.com/demo/ http://speedcurve.com/demo/
