  • Learn@illinois Moodle Service Outage

    Users of the Learn@Illinois Moodle service may have had diffficulty accessing the service from approximately 3:46 PM to about 4:20 PM today, Wednesday, August 24. The ATLAS team is investigating the issue and is taking steps to prevent future issues. We apologize for the inconvenience this may have caused.

  • Possible Intermittent Service

    On Thursday, June 2 there will be a possibility of intermittent service between 5am and 7am due to an infrastructure upgrade. No changes to the Learn@Illinois Moodle service itself will be made at this time.

    The Turnitin service experienced intermittent service in the afternoon of Monday, April 18. The Turnitin support team reports that this lasted for roughly 90 minutes between 3pm and 5pm. This may have affected Learn@Illinois Moodle course sites using the Turnitin service.  Students attempting to submit assignments to Turnitin activities may have been unable to do so in this time frame.

  • Learn@illinois Down for Upgrade

    Due to some small technical difficulties, we were unable to perform the upgrade this morning. These difficulties had nothing to do with the upgrade, but rather with the process of the upgrade.  We are planning on performing the upgrade at 5:30 A.M. tomorrow morning, 11/12/2015.  The upgrade window Thursday morning will be from 5:30 AM to 8 AM.


    The Learn@Illinois service will be down for an upgrade starting at 4:00AM on Wednesday, November 11th. The service will return to operation well before 8:00AM

  • Learn@Illinois Upgrade on Wednesday, November 11th

    On Wednesday, November 11th, starting at 4:00AM (one hour before our normal maintenance window), we will be updating our Learn@Illinois system. The main purpose of this upgrade is to alleviate some of the gradebook slowness that many users have been experiencing this semester, especially in large courses. We anticipate that we will be done well before 8:00AM which is the normal end of our maintenance window.

    While our tests have shown significant improvement in gradebook performance when conducting normal tasks such as moving grades from one column to another, we are going to continue to work to improve performance even more. Making the gradebook even better is still the primary focus of our January 2016 upgrade.

    The major components of this upgrade include:

    • Upgrading the Moodle version from 2.8.6 to 2.8.9 which will capture improvements made by the core Moodle developers.
    • Changing the default so that each grade's contribution to the total score for each student is hidden. This has been a major cause of the slowness that large courses have experienced since this value had to be recalculated any time any grade operation was completed.
    • Not calculating this value when the item was hidden in the Gradebook User Report.

    If you have any questions about this upgrade, please drop us an email at

    Thanks,The Learn@Illinois Development Team

  • Gradebook Slowness Update

    Hello Users,

    We have been working on a solution to the gradebook slowness that has been a big issue this semester, especially for larger courses. We installed an upgraded version on our shadow system that you are welcome to try out. The shadow system is navigated much like production and can be accessed at This system is a duplicate of our production system and is only to be used for testing purposes. Any work that is done on this system can disappear at any time and the database is usually overwritten every night. So please use the shadow system only for experimentation and not to do any work you wish to keep. We would advise against sending students to this system except in very limited cases. Please keep in mind that the shadow system is running less robust hardware than production so performance here will be slower than when it is implemented on production. Also note that the theme on our shadow system looks different than on our production system and that we had a little fun with cat pictures.

    Much of the current slowness seems to stem from Moodle calculating each grade’s contribution to the course total which is a column that is shown on the gradebook user report. This column can be hidden under Course Grade Settings (which can be accessed from the drop-down menu after accessing the course's gradebook), though the current system would still calculate it regardless of this setting. The new version brings three main changes:

    1. If the "Show contribution to course total" is set to hide, this value will not be calculated.
    2. We have made this setting hidden by default for all courses.
    3. Upgrades in the latest version bring additional performance improvements on the backend as well as fixing two grading bugs

    The result of these changes is that gradebook performance is greatly improved. In one test, operation that took ~350 seconds with the old method took ~21 seconds with the new code. The course we tested this in has over 1700 student enrollments.

    We are still in the process of doing final testing on this fix, and we are going to continue to work on making the gradebook performance even better. These fixes will be implemented on our production server on Wednesday morning the 11th assuming the rest of our testing goes well.

    09/17/2014 - 2:25 PM - The slowness that the Learn@Illinois Moodle service has been experiencing earlier today has been fixed.

  • Skipped Roster Sync at 3:00 PM and 6:00 PM

    We generally run a roster sync 4 times a day at 9:00AM, Noon, 3:00PM and 6:00PM. This syncs course rossters in Learn@Illinois with course rosters in the Active Directory (AD) which is maintained by CITES. Since CITES is doing some maintenance on the AD today, the Learn@Illinois administrators decided to turn off our automatic roster syncs at 3:00PM and 6:00PM to make sure that rosters were not adversely affected.

    This means that Learn@Illinois rosters will not be updated until 9:00AM at the earliest. We can still manually add students to course rosters should that be necessary. If you have any questions, or if you need any assistance with your roster, please let us know right away.

  • Learn@Illinois - no need for down time this morning

    The server maintenance this morning went without needing any downtime on Learn@illinois. We had been having some intermittent down time episodes in the last week due to an uneeded  backup file that was not fully deleted.

This should clear up the problem with the intermittent downtimes we have been experiencing. Please contact if you have any questions.
