Due to a mass mailing from outside Ryerson, the RMail and Groupwise systems, as well as other departmental e-mail systems relying on spam and filtering services provided by CCS experienced a considerable slowdown in delivering mail yesterday (Jan. 19). The slowdown began at 6 PM and lasted until after midnight. One server experienced a longer delay until 5 AM.
Measures have been implemented to avoid this particular problem in the future, and we are looking into additional options to reduce the risk of similar re-occurrences.

The perimeter firewall is scheduled to be upgraded at 6:00 am, Friday, December 17. The upgrade is required to correct problems with the session counter and a possible memory leak. These problems may have caused the latency and jitter experienced during real time video and audio applications such as streaming, and video and audio conferencing.
The upgrade will take about 60 minutes. Sessions will be lost during this interruption. Internet access will be maintained as connectivity will fail-over to the back-up link.
We apologize for any inconvenience this upgrade may cause.

On Tuesday, Dec. 28, 2010 between 8:00 AM and 8:00 PM, CCS is planning to upgrade 2 production SAN (storage) appliances to the latest version of the software, as well as applying a number of patches.
These 2 SAN (storage) appliances being upgraded work as a pair which serves storage to many servers. Each appliance will be failed over to the other while it is being upgraded and patched.
During the upgrade process we need to shutdown RMail and Blackboard. All other services should not be interrupted during the fail over. There is still a small chance that a lock up can occur with the servers, which may result in all the storage becoming unavailable to the clients. This risk is low and we have been preparing the environments thoroughly to reduce this risk.
List of services that may be affected/unavailable include:
– RMail *** Unavailable
– my.ryerson portal *** Unavailable
– eHR *** Unavailable
– RAMSS *** Unavailable
– Library eResources *** Unavailable
– all other applications accessed through the my.ryerson portal *** Unavailable
– RMS
– Alfresco
– Virtual Apps (Citrix)
We apologize for any inconvenience this outage may cause.

CCS has scheduled a reboot of our Internet gateway firewall to correct problems related to high-bandwidth video streaming over CANet. The reboot will occur on Wednesday, Dec. 8, 2010 at 6 a.m. All sessions between the Ryerson network and the Internet will be lost as Internet traffic will be re-directed to a back-up link. The reboot process will take up to 30 minutes.
We apologize for any inconvenience the reboot may cause,
