Modules and Unlock Dates Bug

May 27th, 2014 IMG Posted in Canvas Status Comments Off on Modules and Unlock Dates Bug

From Instructure:

We’re tracking an issue this morning where some modules set to unlock by date are not unlocking as they should. The workaround is to access the modules page for the course, click “edit” on the module in question, and then save it; it’s not necessary to make any changes to module settings. This will unlock the module for students.

We’re investigating right now to determine the root cause of the issue and we’ll have a ticket to our engineers shortly. We’ll keep you posted on the status of a fix.

Annotations in Crocodoc Issues in Chrome 31+

November 20th, 2013 IMG Posted in Canvas Status Comments Off on Annotations in Crocodoc Issues in Chrome 31+

From Canvas:

Annotations applied to documents via Crocodoc are displaying poorly in Chrome 31+. The problem appears on both Mac and PC, but it looks a little different on each:

Mac: http://screencast.com/t/r07OdZbC4d
Windows: http://screencast.com/t/xYzoLw7W

We’re working with our friends at Crocodoc on this issue. It’s something they will need to fix on their side. We don’t have an ETA to share yet, but we will keep you informed. Since this is not a Canvas issue, you don’t need to submit further tickets to us about the problem.

Canvas Login Issues (10.15.13)

October 16th, 2013 IMG Posted in Canvas Status Comments Off on Canvas Login Issues (10.15.13)

Users may have experienced login issues Tuesday night between 5:30 and 7:45. There was an issue with the Auburn firewall, the security system that controls incoming/outgoing data, that prevented users from logging into Canvas. However, users should be able to log into Canvas now.

OIT has resolved the issue with the firewall and is implementing new processes to ensure that this sort of interruption does not happen again. Please let us know if you have any questions or concerns.

Connection to Canvas is having issues

September 13th, 2013 IMG Posted in Canvas Status Comments Off on Connection to Canvas is having issues

Auburn’s connection to Canvas is spotty at best.

Instructure has confirmed that an Amazon Web Services network issue is the root cause. Instructure is working with AWS to fix the problem.

Update from Instructure:

The AWS network issue that has been causing slowness for some Canvas users continues. But our Operations team has routed around the problem and all Canvas users should now be seeing normal performance.

We will continue to monitor the AWS issue and take appropriate measures to ensure that Canvas performance stays strong.

Canvas Connectivity Issues (09.03.13)

September 3rd, 2013 IMG Posted in Canvas Status Comments Off on Canvas Connectivity Issues (09.03.13)

Users cannot log in to Canvas at this time. OIT is actively researching the problem and will have it solved as soon as possible.

Update:

You should now be able to log in to Canvas – both from on campus and from home. While the details are still sketchy, it is clear that the problems we encountered today were not Canvas’ fault.

Problems between the Internet2 and Amazon Web Services caused the problems we saw with Canvas this morning; Instructure engineers developed a work around to that problem.

However, one of AU’s internet service providers encountered traffic congestion and connection problems after that problem was fixed. OIT’s network staff monitored the situation throughout the day; they were able to develop a work-around that re-established the connection to Instructure late this afternoon.

We apologize for the inconvenience you and your students experienced today. Please don’t hesitate to contact me if you have questions.

Which Browsers Does Canvas Support? and Firefox Mixed-Medi Guide

August 29th, 2013 IMG Posted in Canvas Status Comments Off on Which Browsers Does Canvas Support? and Firefox Mixed-Medi Guide

Canvas has updated their documentation to help users troubleshoot general browsing issues.

This comes with the announcement that Firefox has changed the way it handles mixed-media. More information from Canvas:

Mozilla recently released Firefox 23 (FF23). This version of Firefox includes new rules and UI related to displaying mixed content. The term “mixed content” refers to things (images, audio, video, etc.) sent using the http protocol but served on a secure page (https). You’re probably getting a lot of tickets related to this change, whether you know it or not.

So what has this change got to do with Canvas? Canvas is served securely, using https. But users can embed or link to things hosted outside of Canvas and delivered via an unsecure (http) connection. (Note that “unsecure” doesn’t mean “bad”; just, well, not secure.)

When a user running FF23 visits a Canvas page with mixed content, confusing things can happen. FF23 prevents unsecure content from running or displaying right away. (Google Chrome has been doing something like this for a while now, but its approach is less aggressive.)

Here’s an example of what can happen in FF23. Suppose an instructor embeds an unsecure video on a course page. Her students using FF23 visit the page and see… no video, just a blank space where the video should be. Nothing is actually wrong; the browser is simply “protecting” the user from the instructor’s unsecure video, without clearly telling them what’s happening.

Discussion Date Unlock Bug in Canvas

June 6th, 2013 IMG Posted in Canvas Status Comments Off on Discussion Date Unlock Bug in Canvas

From Instructure:

Some discussion topics and announcements that are “locked until” are not unlocking as intended

Symptoms

An instructor has set a discussion or announcement to unlock on a certain date / time. The indicated date / time passes, and the discussion or announcement does not unlock as it should. Students who try to access the discussion are shown an “unauthorized” message.

Spotting features

A student reports that they cannot access a discussion that their teacher has told them should be available. Checking the “unlock” date on the discussion confirms it should be available. Masquerading as a student in the course confirms that students see unauthorized messages.

Workaround

Edit the discussion. Change the unlock date (move it backward one day to the day before the original unlock date). Save the change. If desired, edit the discussion again and change back to the original unlock date.

Reporting status

We have enough examples of this problem for our Engineering team to go on, so you can fix these as they appear using the workaround above. There’s currently no need to escalate more examples.

Fix status

Our engineers have identified the root cause of this issue. They are actively developing a fix. We will release it as soon as possible.
