Update at 8:00 AM October 10:
The issue with the network device has been fixed by its vendor and services resumed at 7:55 AM
Update at 10:00 AM October 10:
The issue with the network device has re-occurred at 9:15 AM and the vendor is re-engaged. No Internet access is available
Update at 4:00 PM October 10:
Access to many services were restored in the early afternoon however additional outages are possible before this issue is fully resolved.
Update at 4:45 PM October 11:
Since approximately 11PM on October 9, Ryerson’s network has been under attack. The cyber attack initially caused the failure of a set of devices that are an essential component of Ryerson’s network. The result was a complete loss of Internet connectivity. For a time people on campus could not access the Internet and people outside Ryerson could not access any of Ryerson’s locally hosted online services. Since then our network has been returned to service and CCS has been working with our Internet Service Providers and Network infrastructure vendors to better protect the network from the attack.
As an interim measure we also blocked most traffic originating from outside Canada from reaching Ryerson. This had the unfortunate effect of blocking students, faculty, and staff outside Canada from using Ryerson’s email and other online resources. It also delayed the delivery of email from around the world. Whenever possible we are now gradually relaxing international access restrictions.
While the attack appears to be targeting our network availability we are also looking for signs of other intrusions and for any attempts to compromise other systems.
CCS staff are now doing the painstaking work required to better understand the nature of the attack and further defend against it. We will continue to post updates here as new information becomes available.
Update at 1:00 AM October 12:
Access to Ryerson from most of the world has been restored. We are still temporarily blocking some geographic areas.
Please accept our apologies for the inconvenience these outages have caused.
