Network maintenance - Sunday morning (EST) Feb 12, 2012

The University of Michigan central IT organization, ITS, will be upgrading the network gear that connects ICPSR's building to the campus data network.  The work is scheduled to start at 6am (EST) on the morning of Feb 12, 2012 and should take between one and two hours.

The ICPSR IT team will redirect traffic from the production system to our cloud replica during the maintenance period.  The replica runs in Amazon's cloud and features services such as search, analyze, and download, but purposefully does not enable features such as deposit.

Between the cut-over to the replica, the network maintenance, and the fallback to the production system, access will likely be a little rocky next Sunday morning.  Like a freeway during construction, if it is possible to take a detour around ICPSR's web site on Sunday morning, that's the safest route.  But if you find that you need to download some data or use the site, the replica will be available.
