University of Oregon Information Services plans to upgrade the web servers operation system, which will cause some university websites to be offline for one to four hours beginning at 5 p.m. Feb. 21.

All Drupal websites on campus, including the UO homepage and admissions websites, will be offline during this time. This will not disrupt UO Blogs or UO Pages websites. All websites should be back online by 10 p.m.

Offline sites will show the message https://blogs.uoregon.edu/servicesoffline/. Information Services advises website managers to make any updates to their sites before 4 p.m. and refrain from sending emails that direct people to their sites that day.
