Cory Hall 4th Floor Wireless Coverage

by

Due to construction on the 4th Floor of Cory Hall, wireless APs are being removed on the South side of the floor. Consequently, there will be limited WiFi access there to all WLANs. Wireless service will continue in the area around the BSAC office and labs in the immediate vicinity to BSAC. New APs will be reinstalled once the area is remodeled and ready for occupancy again.

certificate revocation lists

by

A RA (Registration Authority)
account in Europe was compromised
last week (March 15, 2011) and
nine rogue SSL certificates were generated.

These rogue SSL certificates have been
revoked via a CRL (certificate revocation list)

Microsoft issued a Security Advisory March 23, 2011

On devices with automatic Windows Update enabled, it appears
the above CRL was imported into Internet Explorer.

It is also possible to manually add or check that the CRL
has been added to one’s browser –

Internet Explorer

Firefox (3.x or 4.0)

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
