Slow Internet access on Wednesday September 28, 2016 at 3:25 PM

On Wednesday, September 28, 2016 at 3:25 PM CCS received reports about slow or intermittent internet access.  Network services team is investigating the issue.

Update:

The network services team tuned some traffic threshold parameters and services resumed at 4:00 PM

Update October 3, 2016:

The Internet outage on September 28, 2016  was the result of a Distributed Denial of Service (DDoS) attack. The attack was first reported at approximately 3:14 PM. DDoS network traffic is designed to stress networks and servers to the point that they become unavailable. In response, CCS began to aggressively filter network traffic until Internet access from inside Ryerson was restored and the DDoS attack subsided.

During the initial stage of the attack people attempting to access the Internet from on campus were not able to do so or found access extremely slow. However, anyone off campus was still able to connect to Ryerson’s core services such as the my.ryerson.ca portal.

By 3:37 PM, when Ryerson began aggressively filtering network traffic, a small number of people were no longer able to access Ryerson from off campus. At the same time network access from on campus was restored. 

As a safety precaution, a moderately aggressive level of filtering was left on overnight. This caused connection issues for a relatively small number of people trying to connect to Ryerson during the morning of Thursday September 29 until approximately 10 AM when filtering was adjusted back to normal levels.

CCS is analysing the attack and our response to it and will work to improve our response to DDoS attacks in the future.

Google’s “Important changes to your account” notice

Google has started displaying a one-time notice that your Ryerson account now “works more like a full Google account.” Google is displaying this notice now because of a change in how the Google Play store has been configured by Google. The announcement does not change Ryerson’s agreement with Google or change who can access your email, calendar or Google Drive. Pressing the “Agree” button does not mean you are consenting to any new access of your account by anyone at Ryerson or at Google.

Ryerson’s agreement with Google only covers Ryerson’s use of what Google calls its “core” applications. The core applications includes Gmail, Google Calendar, and Google Drive. Ryerson disabled access to all non-core apps from the beginning of our use of Google Apps for Education. However, Google did not provide Ryerson with a way to disable the Google Play Store even though it was not a core application. Recently Google made it possible for Ryerson to disable the Play Store but we chose to leave it available to avoid the problems disabling it might create. As a result this notice is appearing because access to the Play Store presumably means your account “works more like a full Google account” rather than as an account that can only access core applications. In other words you now have access to a non-core service.

When the notice appeared we opened a support ticket and asked Google if disabling the Play Store would mean that the notice will no longer appear. Their response was no.

While this is a frustrating situation – as the notice is only really relevant for people who use their Ryerson account to access the Play Store – we recommend that you press “Accept” in order to get rid of the notice. Google has said the notice will not appear again after you press “Accept.” Pressing the accept button only means that you have seen the message and does not mean you are consenting to any new terms and conditions regarding the use of Google’s core applications.

Finally, the notice includes this text: “your domain administrator will have access to your account information, including any data you store with this account in Google services.” The domain administrators are CCS system administrators who administer Ryerson’s use of Google Apps for Education. They work in much the same way as all system administrators in CCS that manage systems like D2L, RMail, and the my.ryerson.ca portal. Their use of the system is monitored and they do not use their system administration privileges to access any data you store on any of our systems unless authorized to do so in exceptional circumstances – for example if Ryerson is served with a search warrant that has been validated by Ryerson’s General Counsel.
