8:10 p.m.

OIT has identified an issue related to network equipment and has implemented a fix. We are monitoring progress to confirm service has been restored.

5:20 p.m.

The response to the ongoing OIT disruption continues. OIT is engaging with the respective vendor(s) and continues to investigate. 

Many Princeton University applications and services are unavailable. At this time, it may not be possible to use the single-sign-on service to sign-in to applications. Campus WiFi via the eduroam network and Research Computing systems are also affected.

Critical life safety systems such as the fire alarm system and 911 remain operational, but the OIT team has identified that some desk phones are no longer connected to the network. For that reason, the University recommends mobile phones to reach 911 or emergency services.

Additional personnel from Public Safety and Facilities will be on campus until the outages are resolved.

Due to the unavailability of some systems related to remotely monitoring building access, the following actions will be taken this evening:

• Administrative buildings were manually locked at 5 pm. Card access is disabled.
• Academic and research buildings will be manually locked at 8:30 pm.  In the meantime, local alarm systems such as fume hoods and refrigeration alarms may not work in these buildings. After 8:30 pm, these buildings should be vacated. Only emergency access will be permitted after this time.
• Residence halls will remain on their normal locking schedule. Students should make sure to bring their TigerCards when leaving their buildings as systems enabling temporary cards are not functioning.  
• Firestone Library circulation will remain open until 9 pm and the study areas will be open until 11 pm. Firestone Special Collections, the Milberg Gallery, and the Cotsen Children’s Library are closed for the remainder of the day.
• Campus recreational facilities will remain open as scheduled.

5:10 p.m.

Our team has implemented a temporary workaround, enabling off-campus sign-in access to cloud-based solutions, such as Zoom, Canvas, GlobalProtect VPN, and ServiceNow.

3:30 p.m.

Investigation into the disruption continues. The issue may be related to hardware that controls internet traffic. OIT is engaging with the respective vendor(s) and continues to investigate.

2:10 p.m.

Our team has also identified that some desk phones are no longer connected to the network. For that reason, we recommend using mobile phones to dial 911 or reach emergency services. 

1:43 p.m.

The data center cooling has been restored. It may take at least 12 hours for Research Computing storage to come back online.

1:22 p.m.

OIT is also investigating overheating equipment in the data center. At this time, Research Computing equipment is being shut down. Additional updates to follow. 

1 p.m.

Investigation into the disruption continues. The issue may be related to hardware that controls internet traffic. OIT is engaging with the respective vendor(s) and continues to investigate.

12:30 p.m.

Technicians are currently restarting various systems and equipment as we work to identify the root cause. We are working to restore service as soon as possible. 

12 p.m.

OIT continues to investigate the root cause of the service disruption and is working to restore service as soon as possible. 

11:20 a.m.

OIT continues to investigate the root cause of the service disruption and is working to restore service as soon as possible. 

10:30 a.m.

The Office of Information Technology is investigating a service disruption affecting several applications and services. Additional communications are expected as impact and restoration information becomes available.

Many Princeton University applications and services are unavailable. At this time, it may not be possible to use the single-sign-on service to sign-in to applications.
