IMAP/mail, home/project, Windows services (AD/WINS/printing), LDAP/NIS/DNS, DHCP and most other IDSG and IMG services will be affected. We will try to keep some basic network services running (DHCP, DNS/NIS), possibly in a reduced capacity.
While EECS-Secure, EECS-Guest and EECS-Open wireless LANS will be out of service during this time, the EECS and AirBears wireless LANS will remain operational during the outage.
The reason for this extended downtime is multi fold. The first is to repair the UPS that failed a couple of weeks back. The repaired unit will be placed back on line and extensive testing must be done to ensure it’s operation before we can depend on the UPS again. The second is to move data around which will allow us to remove from service a piece of software used to manage storage. This software is no longer under development and we need to remove our dependency on it. Lastly, some routine maintenance will be done which can only be done when systems are down. These are the kind of things that can only be done between semesters and we ask for you understanding during this disruption in service.
While the stated outage is from 10:00AM to 9:00PM, it may not take that long. This is a worst case scenario. If possible, services will be brought up sooner than 9:00 PM.

Some of the issues with yesterday’s upgrade could not be resolved yesterday, so we’ll be addressing them today. We expect the services to stay up, but there could be minor delays/slowdowns or short outages.

On Saturday, June 6th, we will be doing major upgrades to some of our
backend systems. This work will start at 10 am. We expect that some of
services will start coming back up in about 3 hours, but due to the
complexity and extensiveness of the upgrades, the downtime may extend well
beyond the 3 hour mark. These upgrades are imperative for the continuing
reliability of the infrastructure services. We apologize for the
inconvenience.
The following services will be affected:
* Home directories
* Project space
* UNIX SWW
* Departmental/IDSG web servers
* IMAP (due to the additional work, IMAP will be down for an additional 2 hours)
* argus/login (UNIX login servers)
* Department websites www.eecs / www.cs and all hosted project sites
* Department mailing lists hosted on lists.eecs
* buffy and all ACG applications
* wikis hosted on wiki.eecs
* Department’s jabber server, jabber.eecs
