Scheduled Maintenance

Campus Wireless Upgrade Jul 19, 2025 22:00 - Jul 20, 2025 06:00 EDT

CCS will be performing vendor-recommended software updates to the campus wireless systems to support new wireless hardware and features, from Saturday, July 19 at 10:00 p.m. to Sunday, July 20 at 6:00 a.m. Several short interruptions (approximately five minutes each) of wireless services are expected during this maintenance window.

CFS Active Directory Maintenance Jul 22, 2025 06:00-08:00 EDT

The CFS Active Directory domain will be undergoing maintenance. No service interruption is expected.

The CFS Active Directory domain is the main Microsoft Windows Active Directory domain on campus. CFS AD is primarily used to authenticate users to computers and provide file and print services. It is also used to synchronize users and provide user authentication to other systems, such as secure WiFi (uog-wifi-secure and eduroam), VPN, and telephony and voicemail services.

Telephony Service Maintenance Jul 25, 2025 21:00 - Jul 26, 2025 00:00 EDT

As part of the Telephony Migration Project, we are planning two brief maintenance windows to support the ongoing transition to the Cisco cloud-based phone system:

• Friday, July 25, 2025 – 09:00 PM to 12:00 AM
• Sunday, July 27, 2025 – 6:00 PM to 11:00 PM

Will this affect me?
During each window, all desk phones across the Guelph and Ridgetown campuses will reset twice.

Expected impact: brief phone downtime of approximately 1–2 minutes per reset.

What should I do?
No action is required from users.

Questions?
We appreciate your cooperation and understanding as we implement these necessary improvements. If you have any concerns, please contact the CCS Help Centre at uoguel.ph/IThelp.

Campus DNS Service Maintenance Jul 26, 2025 00:00-04:00 EDT

On July 26th, from 12 am to 4 am, CCS will be making change to the campus DNS service infrastructure. This change is part of our continuing effort to migrate to private IP addresses and consolidate our remaining public IP address space.

What is being changed during this maintenance window?

• The DNS server settings for IP addresses 131.104.136.11 (asterix.net.uoguelph.ca) will be changed to 131.104.88.11.
• The DHCP configuration will be modified with new IP addresses.
• Systems using 131.104.136.11 as DNS server will have DNS service interruption.

Note: The DNS servers at 131.104.20.10 (obelix.net.uoguelph.ca) and 131.104.88.10 (willow.net.uoguelph.ca) will remain unchanged.

What action is required?

Most users will not be affected. No action is required if your systems use DHCP (automatically assigned IP addresses and DNS servers). The Network Infrastructure team will update DHCP configurations to reflect these changes automatically.

Action is required only for systems with manually configured static IP addresses. This typically includes:
• Servers (physical and virtual)
• Specialized workstations
• Network equipment
• Other systems with static network configurations.
If you manage systems with static IP addresses, you will need to update the DNS server settings from 131.104.136.11 to 131.104.88.10 before July 26th.

Wireless Authentication Server SSL Certificate Renew
Completed - The scheduled maintenance has been completed.

In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Jul 15, 06:00 EDT
Scheduled - On Tuesday, July 15, from 6 to 8 a.m., CCS will be renewing the SSL certificate for the wireless authentication servers. As a result of this change, when users access campus WiFi at any U of G campus after July 15, including main campus, Ridgetown campus, and the University of Guelph-Humber, there will be some action required for them to connect to their appropriate campus network (uog-wifi-secure and eduroam).

We will be sending a mass email that includes the user instructions below.

What will happen when users access campus WiFi after July 15:

Most users will be prompted: Upon first attempt to connect, most devices will see a one-time-only certificate warning. Users will simply need to accept the new certificate when prompted to do so and should then be able to connect.

For users who are not prompted: Certain devices may not prompt users to accept the new certificate. These users will need to manually reconfigure their devices to join, based on their regular WiFi network.


Ideally users do not wait to be prompted and follow the instructions below prior to July 15. This can be done from home and will apply the new certificate. It should provide a seamless connection upon return to campus and will avoid security risks when they go to accept the certificate. If they do wait and accept the certificate after July 15, please encourage your users to verifying the certificate against the information on this CCS network requirements page: https://uoguelphca.sharepoint.com/sites/ccs/SitePages/internet-phones/wireless-internet/wireless-requirements.aspx?

How to manually configure user devices to join:

The majority of Guelph campus users who use uog-wifi-secure should access the JoinNow tool prior to July 15 by following the instructions at https://www.uoguelph.ca/ccs/securewireless

Users at University of Guelph-Humber and others who use Eduroam should use the Eduroam-CAT tool prior to July 15 by following the instructions at https://cat.eduroam.org/

As we do not know which devices will be prompted and which will not, we highly recommend users reconfigure their devices before July 15 using the links provided above.

If you have any questions or concerns, please contact the CCS Help Centre at IThelp@uoguelph.ca.
