SAMHDA Web site unavailable on Sunday, Jan. 15 between 10AM and 12PM

ICPSR will be upgrading Web server hardware Sunday, January 15 between 10am and noon (Eastern Time). During this time all Web sites hosted by ICPSR, including SAMHDA, will experience significant downtime.

The goal of the maintenance is to replace the old 32-bit production Web server with a new 64-bit system with significantly more processing power and memory. The move from a 32-bit platform to a 64-bit platform also requires a number of software upgrades.

Please contact web-support@icpsr.umich.edu if you have any questions.
