Staff responded to automated alerts, and were able to bring the SAN back online. The precise cause of the outage currently remains unknown.

Delivery is expected Monday for our new UPS which will be installed in the 290 Soda Hall server room. Some services will be down for short periods on Tuesday while they are moved off of room power and onto temporary power. Later in the week, there will be a second outage while those machines are moved onto the new UPS. Additionally, there may be a longer outage of our storage systems while some upgrades are done.
While I realize that this post is somewhat vague, a lot depends on exactly when the UPS is delivered and how long it takes to install it. I will be posting more refined notes to narrow down the scope of what services will be out (and when) as time goes on.
While we realize that there may be some inconveniences for some, please bear with us as we strive update our services and minimize outages for the future

Some electrical work in 290 Soda caused the unexpected downtime of several IDSG services, including Home and Project Storage, Departmental Webservers, and others. The power has been restored. Some services are still being restored.
Work was in preparation for a new UPS system in the machine room. This involved moving some circuits on systems that have redundant power. There were not expected to be any outages at this time.

There will be a short, scheduled maintenance/upgrade on home and project for the hour specified. IMAP will also be affected by this upgrade. The reserved downtime is 1 hour, but most likely the actual downtime will be less.

We are currently experiencing issues with IMAP, Home, and Project Storage. Staff are currently working on resolving the issue. News will be posted when services are restored.
There has been an outage on project and IMAP server earlier today. While the service has been restored, we are continuing to monitor it and investigate the root cause. Depending on the vendor recommendations, we may have to schedule additional work on a relatively short notice.
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.
