ITHACA -- From 4 p.m. Saturday, Sept. 24, through noon Sunday, Sept. 25, many Cornell University central computing services will be unavailable, including e-mail, Cornell University Library online services, CUinfo, uPortal.Cornell, Blackboard, the electronic directory and Cornell mailing lists. The outage is due to the installation of an upgrade.

For the complete list, see below or go to http://www.cit.cornell.edu/computer/news/articles.html#sept24outage.

Cornell Information Technologies (CIT) recommends that people plan on not using centrally provided computing services during the outage since most will be unavailable. However, networks within residence halls and buildings (except Rhodes Hall) will continue to function, as will access to non-Cornell Internet services. Dial-up service (EZ-Remote and Express Lane) to the Internet also will be available.

Other central services that will remain operational during this time are EZ-Backup, RedRover (wireless), CUTV, Kronos time clocks, Kerberos, CUWebLogin and CUWebAuth, the Permit service, DHCP and DNS (domain name system). All other services provided to the campus from the Rhodes Hall machine and node room will be unavailable; see the list for details.

This outage is necessary so that CIT can install an uninterruptible power supply (UPS) in the Rhodes Hall machine and node room. The UPS will provide a needed increase in capacity. Inserting the UPS into the building's electrical infrastructure requires a total power interruption in Rhodes Hall.

Before the outage, questions or concerns can be sent to serverfarm@cornell.edu. During the outage, concerns or questions can be directed to 255-9900.
