CARLI services interruption Tuesday Oct. 25

On Tuesday, October 25, 2022 at 5:30pm, some CARLI services experienced an unexpected service interruption for approximately 10 minutes. Services affected included the CARLI website, the ILDS website, the CARLI Selection System, CARLI’s Explore More Illinois authentication service, and CARLI’s ticket tracking system.

During routine software maintenance of CARLI’s AWS environment, new local IP addresses were unexpectedly assigned to these services. While CARLI staff corrected the problem quickly, users may have experienced an outage longer than 10 minutes while waiting for DNS caching to be updated locally.

For future maintenance of this type, CARLI staff will perform the updates on weekends to avoid any potential unexpected downtime.
