ITS has implemented infrastructure changes to permit high availability capabilities for our services.
Contemporary IT system and service robustness is best accomplished through a three tier model consisting of 1) effective design and professional practices 2) high availability through infrastructure and operating diversity 3) disaster recovery as an insurance strategy using an external vendor specialist. The first strategy has been our historical approach and the organization is actively pursuing the third strategy. ITS has added high availability capability by implementing custom network connectivity between our primary data center in Gant and our secondary machine room in HBL. This multi-site data center capability allows us to deliver virtualized services from two independent locations as a single extended offering.
Our primary data center in Gant will undergo disruptive upgrades to both power and environmentals this weekend that will result in a 12-18 hour loss of services from this location. By diversifying a number of our generically consumed services between our paired data centers using our new high availability infrastructure, UTIS will be maintaining the following services without substantive interruption during the upgrades to the Gant data center.
Networking (wired and wireless)
Email (Microsoft Exchange)
Authentication (NetID, AD, Radius, CAS, etc)
Departmental web content management (Aurora)
University core websites (alert, it status, today, uconn)
Delivery from the secondary HBL location will begin almost immediately as the primary delivery location is shutdown. Any disruption of these services during failover will be extremely brief and should be virtually unnoticed. Outages have an increasingly disruptive impact on our community and we will continue to pursue high availability as well as other architectural and operational strategies to improve the performance and stability of ITS systems and services.
ITS has increased the sensitivity of the UCONN email spam filters to more effectively prevent the delivery of unwanted messages.
The university email challenge has always been to correctly identify and prevent the delivery of unwanted messages without misidentifying and blocking wanted messages. Recent feedback from our community indicated that the system was permitting the delivery of too much spam. ITS carefully assessed the service configuration and implemented adjustments this morning to improve its filtering performance. Our tests indicate that this will safely reduce spam delivery by approximately 20%.
Please do not hesitate to contact us or the ITS Technology Support Center if you have questions or concerns or if you believe that your email is being blocked incorrectly.
ITS has enabled guest access to WhatsUp, the university network monitoring system.
ITS network technicians utilize WhatsUp to monitor the current status of more than 3,000 network devices in our data network. This tool is not designed or intended to be a generally consumed service at the University, but it is possible that it might be useful for other IT professionals. We have enabled read-only access to WhatsUp from any campus network. You may login using “guest” as both the username and password. Off campus access to this resource requires use of the University VPN service.
The six minute limit on ITS Technology Support Center phone system hold times has been discontinued.
This limit was originally created to address feedback pertaining to long holds, but it has become clear that it is not the optimal way to deal with this issue and it has the unintended side effect of forcibly disconnecting people who might have preferred to continue holding. ITS wants to make it easier for the community to access help resources, and so callers on hold will be periodically prompted with three options:
ITS will continue our review of help desk processes to increase call throughput, but in the interim we believe that the range of options above will better meet the different needs of individual callers.
There will be a two-week ITS moratorium on network and system changes starting today, Friday, May 2, through Friday, May 16.
We understand that this time of year is a critical period with students and faculty trying to meet end of semester obligations. ITS has imposed significant restrictions on changes to systems and services that might have a production impact in order to minimize potential outages during this high anxiety period. Changes required to respond to emergent situations will be duly evaluated and pursued only if their need is significant.
There are a number of general phone and email contact points that provide access to ITS groups and / or services. When submitting a help or service request, we encourage everyone to contact the organization through either the Technology Support Center or one of the local Service Areas. However, we have received feedback that these mechanisms are not always helpful when trying to contact specific individuals. Now we're changing that.
ITS is now aggressively ensuring that individual phone numbers and email addresses will be properly available in the University's online phone book. We will also maintain a staff directory, as we want the community to be able to easily contact us at both the organizational and individual level for all of their IT needs.
ITS has added authentication support to its Simple Mail Transfer Protocol (SMTP) server, resulting in more flexibility and convenience for SMTP users.
Customers that utilize Outlook and Exchange for email already take advantage of authenticated access for outgoing emails, but our generally available SMTP server has not historically supported authenticated access. A consequence of this is that ITS blocks access from off-campus locations to the SMTP server when sending emails. This limitation has required laptops that access the SMTP server directly from off-campus locations to either have a separate configuration using a different SMTP server or to utilize the University's Virtual Private Network (VPN) when sending email. Enabling authentication capabilities on the SMTP server allows ITS to fully support direct access to the SMTP server from areas outside of our network, limiting complexity and potentially reducing the support needs of our community.
Mail clients configured to utilize smtp.uconn.edu directly can use SMTP authentication through either SSL on port 465 or STARTTLS on port 587. The authentication credentials are simply your NetID and password. Outlook or other clients that use Exchange directly will not require reconfiguration and adjustment – they will simply continue to operate as they do now.
For assistance on configuring ports for SMTP Authentication, users can contact the ITS Technology Support Center by submitting a ticket at http://serviceit.uconn.edu.
ITS has procured an InCommon Certificate Service for the University in response to the recent Heartbleed exploit in the OpenSSL cryptographic software library. This service allows us to generate, for all UConn Domains, an unlimited number of certificates (e.g., SSL, extended validation, client, and code signing) that are validated by a trusted Certificate Authority.
Technical staff across the Institution aggressively responded to the recent Heartbleed exploit and updated University servers. Heartbleed attacked an OpenSSL vulnerability in order to obtain private data. It is possible that some certificates were compromised and it would be wise to replace any that might have been exposed. You may replace your certificates at no departmental cost by using the ITS fully subsidized InCommon Certificate Service.
Additional information on the new service can be found at https://its.uconn.edu/ssl-certificate-service/.
The SafeConnect environment has provided a number of operating and management benefits to the university. It has, however, also generated a significant number of support problems for the community. ITS recently deployed a new version of the environment. It did not adequately address the long-standing support challenges and, after careful consideration of the product and based on direct feedback from the community, it has been permanently disabled. ITS will pursue other, less intrusive, approaches to replace the capabilities that SafeConnect previously provided.
The SafeConnect client that is currently installed on computers will no longer prevent access to the university network and it may be uninstalled at your convenience. If no action is taken, it will automatically uninstall itself after approximately six months of inactivity.
The IT Partners program is a streamlined governance structure consisting of three standing committees that are organized to provide clear roles, to prevent overlapping effort, and to align participants to focus areas. They provide oversight of University Information Technology and Services (ITS) systems and services and are advisory to the University CIO regarding the efficacy of existing or proposed central IT initiatives.
