RMAIL Delivery Slowdown

Posted on January 20, 2011 by

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.

Emergency upgrade to perimeter firewall

Posted on December 16, 2010 by

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.
