by

The IRIS dhcp server will be down for maintenance on
Wednesday September 30, 2015 from 7am to 7:30am.
Devices with existing leases / IP assignments
on the IRIS wired and wireless networks
will not be affected. Devices broadcasting for
dhcp support will not be able to obtain an
IP assignment during the maintenance period.
We do not expect to need the full thirty
minutes for maintenance. New hardware is
being deployed to replace the old hardware
supplying DHCP service.

Miscellaneous services affected by project space outage

by

Last night’s outage of project.eecs caused a few other services to misbehave this morning. We believe all services are functioning as of around 11am.

An automatic process that generated configuration files for our DHCP server was generating truncated files, causing DHCP service to be out for some clients. That was resolved around 9:15am.

The server iris.eecs had some email stuck in its queue related to recent laptop purchase requests. Fixing that required a reboot of the server, and iris.eecs was down from around 10:30am until around 10:50am.

The ACG application server buffy.eecs apparently hung last night due to the project.eecs outage. It was rebooted this morning around 9am.

UPS Installation/Various System Outages

by

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
