Intermittent network access for the Ryerson’s residence at Jarvis St.

Posted on September 20, 2018 by michael

On Thursday September 20, 2018, CCS received reports about intermittent network connectivity from Ryerson’s new residence on Jarvis St. to the main campus. The problem has been traced to the large amount of traffic originating from a small set of remote IP addresses in the residence being throttled by one of our network security devices. The device has been adjusted and CCS is monitoring network performance.

We apologize for the inconvenience this problem has caused.

Wireless authentication failure on Tuesday September 4, 2018 at 7:50 AM

Posted on September 4, 2018 by michael

On Tuesday September 4, 2018 at 7:50 AM, CCS monitoring systems indicated there is a very large number of wireless devices failing to authenticate. Network Services team is investigating the issue.

Update 3:35 PM: Despite working with our wireless vendor we have not been able to isolate the problem beyond the fact that the login process is not working. As a temporary solution we are working towards making available a separate wireless network called RU-Wireless. Please use it once it becomes available until we resolve the problem with RU-Secure.

Update @ 11:20 AM, Wed, Sept. 5: The RU-Secure network is available and we are monitoring it closely. Once RU-Secure has shown to be fully stable, the temporary RU-Wireless network will be turned off. At that time, please use RU-Secure. The problem was traced to how our wireless system was communicating with the servers it uses to validate usernames and passwords.

Update @ 12:58 AM, Wed, Sept. 5: The RU-Wireless temporary network has been shut down. Please connect to RU-Secure. If you have never successfully connected to RU-Secure please see our online instructions.

We apologize for the problems this outage has caused.
