ICPSR Web Server reboot today - 2pm EST - Feb 19. 2010

We've noticed an elevated level of transient errors with our production web server. This is likely causing a small performance problem for some web site visitors, and is also generating sporadic false-positive notifications from the University of Michigan's Network Operations Center.

We're rebooting the web server at 2pm EST today (Feb 19, 2010). We believe this will clear the transient errors, and improve performance. We've elected to perform this maintenance in the middle of the work day (USA time) so that the entire team is available to diagnose and treat any unexpected problems once the web server restarts. This includes systems such as download, search, the Summer Program portal, and so on.

We expect a brief outage lasting only a few minutes.

Our apologies to our web site visitors for the inconvenience this will cause.
