A small number of Mac users have expressed some intermittent issues while connecting to the Wireless RU-Secure and RYERSON networks, as well as the Wired captive portal network on campus. The symptoms are showing as declined connection and/or not being able to download the authentication web page.
After looking into the problem, CCS has discovered that there is a issue with OSX 10.7.2 (Lion) in regards to HTTPS, WPA2 and captive portal certificate handling.
The solutions offered by Apple/Mac involve disabling the security checks of the certificates within browsers or within the Key-chain itself. CCS does not recommend taking this action as it leaves the user’s computer vulnerable to unverified certificates. CCS will continue to investigate the issue.
We apologize for the service interruption.

A failure with one of the UPS (Uninterrruptible Power Supply) systems in the data center caused a number of servers to loose power, due to lack of power source redundancy. The incident happened around 6:00 PM. Technical staff are restoring services as quickly as possible.
Affected services included RAMSS and the Finance system, as well as a few other services (e-mail scan servers, some web services). Some of the e-scan services were not affected due to redundancy of servers in other data center locations. Most other services have been restored. We’re still working on RAMSS and the Finance system.
Update: RAMSS service was restored as of 9:20 p.m.
Update: OGF and Markview services were restored around 10:15 p.m.
We apologize for the service disruption.

Some time after 7 PM today CCS began receiving reports that GroupWise was no longer delivering or sending Email. Staff are on the way to campus to investigate.
Update: 9:15 PM: The GroupWise gateway server, responsible for receiving and sending mail, rebooted itself some time around 5pm. It’s services did not start automatically so were down until they were manually started at 8:45pm. Email that was delayed should already be arriving in GroupWise mail boxes and outbound mail that was not sent earlier is now being sent.
A GroupWise process hung last night, around 11:45 PM, causing web client access to fail when connecting to GroupWise. Services were restored at 8:10 AM, Wednesday, Jan. 4.
We apologize for the service disruption.
