When key services are down, it's nice to be in the know. The Office of Information Technology (OIT) would like to take the opportunity to make you aware of the various communication channels OIT uses in outage situations to keep you informed.
By bookmarking and subscribing to these various channels now, you’ll ensure that you are in the know during unplanned outage events.
The Office of Information Technology is improving the network registration system on our campus. The next phase will involve deployment on the campus wireless network in academic and administrative buildings starting on May 15. OIT knows that the campus network, including UCB wireless, is a resource you rely on for accessing a wide variety of university and Internet resources. Keeping the network secure is critical to making sure the network is available and reliable. Network registration is an important part of keeping the network secure.
In the effort to improve our campus network infrastructure so that it can support faster network speeds, the next step will involve upgrading network switches across the campus. From September through November, the Office of Information Technology (OIT) will work in coordination with a local contractor to upgrade network switches in buildings throughout campus.
Over the next several months OIT will be working to update how computers authenticate when connecting to the campus wireless network and the wired networks in the residence halls. The existing network registration system, which ties a computer’s MAC address to an Identikey, has been in place for many years. Due to performance and security concerns the system needs to be replaced. To minimize the impact to the campus community the new registration process will closely resemble the existing network registration process, and this change, once in place, will be largely transparent.
The Office of Information Technology (OIT) has upgraded the campus’ Student Printing and Scanning (SPS) system to give you better, more convenient print drivers, locations and capabilities.
Get The New Print Drivers Now!
With just seven standard types of student printers, you no longer need to manage a potentially large number of print drivers.
The data center firewall in the Computing Center must be upgraded to higher performing hardware and this will take place on the night of January 3 from 10 p.m. to 2 a.m. Upgrading a firewall makes services protected by the firewall unavailable while the hardware is replaced and the services brought back online.
You have successfully connected to the CU-Boulder network.
The CU-Boulder campus network registration service is going through a phased upgrade. This upgraded registration service will periodically require reregistration. If you have questions about the new network registration service or the reregistration process, please contact the IT Service Center. Contact information is at the bottom of this page.
CU-Boulder is "closed" network meaning that, by default, traffic is not allowed into the campus network with the following exceptions:
*NOTE: None of these changes impact outgoing Internet traffic (for example, web browsing, connecting to external mail servers, etc) only traffic from the Internet attempting to connect to campus systems is affected.
The campus border firewall is part of a comprehensive and broad-based OIT security program to protect campus users from malicious online attacks. A firewall is a device or set of devices designed to permit or deny network transmissions based upon a set of rules and is frequently used to protect networks from unauthorized access while permitting legitimate communications to pass.
Campus units that need to provide access to services from the Internet can request an exception; however, departments are strongly encouraged to use the VPN service as an alternative to seeking a border firewall exception.
To most desktop users the firewall does not have an impact on daily operations. An exception would be for those that need to access some on-campus services, such as Windows Remote Desktop, from an off-campus location. In this case, use of a VPN client is necessary to connect to your computer or other campus resource. Learn more about using the campus's VPN client.
The campus VPN service now includes a mobile app that allows Apple devices to use the VPN. Junos Pulse is a free application available in the Apple App Store. The campus VPN allows you to make a secure on-campus network connection, when you are off campus or on UCB Wireless, so you can access restricted campus services such as library resources or file servers. Currently CU-Boulder does not officially support a VPN option for Android users. Although, there is a Junos Pulse application for Android, it does not have full functionality and is not recommended.
CU-Boulder offers a couple of different solutions for using an application to use in order to have a secure on-campus network connection when you are away from campus. These applications are available for all CU-Boulder affiliates with an IdentiKey. Refer to the information below in order to select the best solution for your needs.
|Network Connect||An application that you can install and use to have a secure on-campus network connection when you are away from campus or on UCB Wireless. Use this application to access on-campus resources and still have access to your home networked devices.|
A VPN solution is available for CU-Boulder affiliates using Apple Devices. Junos Pulse is a free network client application that allows for mobile devices to connect to CU-Boulder's VPN. Android devices are not currently fully compatible with CU-Boulder's VPN service.
The same UCB Wireless service that you use accross campus is now available on the Buff Bus and at Buff Bus stops. Learn more about UCB Wireless.
Now you can hop on the Buff Bus and the campus wireless network at the same time. That’s because for the first time, UCB Wireless is available on the Buff Bus. You connect to it just like you connect to UCB Wireless on campus. Using UCB Wireless allows you to access campus resources, such as file servers or library resources, which are restricted to the campus network.
OIT is conducting emergency maintenance tonight to restore uninterruptible power to the data center in the Computing Center on the east campus. The Uninterruptible Power Supply (UPS) device that serves the data center requires emergency maintenance. The data center houses the equipment powering many services for the campus. We will bring these services down tonight, Friday, August 26 at 8 p.m. and are anticipated to be restored 8:00 a.m., Saturday morning, August 27.
