OIT: OIT will be mirroring our efforts to make sure that their equipment in the buildings are available during this period.

Although we will do our best to avoid downtime of critical services during this period, there are many factors that may intersect unexpectedly to cause an outage. Please send email to if you are concerned that this work will cause a hardship on your research and we will work with campus facilities to do our best to accommodate.
