My team has built the video portal portion of the system. The portal enables a researcher to play a list of videos that s/he has selected to view based on an analysis of the associated quantitative data and tagging data. Access to the video and datasets is restricted and requires one to complete a data use agreement via ICPSR's web-based request system.
Ever since the recent craziness with vulnerabilities in Java plugins, I've making a concious effort to use Qualys's browser checker - https://browsercheck.qualys.com/ - on a routine basis both at home and at the office.
Installing the tool in your browser is very easy, and the service is free and painless to use. I have been using it to both to determine if my current browser and plugins are up to date, and also to identify plugins that are installed and enabled, but which I don't really need or use (e.g., Silverlight which I often disable for long stretches at a time).
Qualys generates a nice report
like the one above to let you know if everything is up-to-date.
ICPSR's content delivery system showed very high availability in March 2013: a bit over 99.95% uptime. We had only two problems in March. One was a power outage that affected our headquarters on the University of Michigan campus, and we experienced a small amount of downtime as we moved service to our replica in Amazon's cloud. The second was a 21-minute outage due to a continuing -- but now solved, we think -- problem with exporting content from our Oracle database server.
Here are the overall numbers for ICPSR's 2012-2013 fiscal year:

We replaced our aging Oracle database server with a new machine which has twice the memory, twice the computing power, and perhaps most impressively, has 300 times the disk I/O speed(!). The new machine has an array of solid-state drives (SSDs), and we use this for all of our database storage. (The operating system resides on conventional disk drive technology.)
