Linewize Outage History

Linewize experienced an over-blocking issue that prevented access to websites that should have been allowed, affecting the School Manager component. The engineering team investigated and resolved the problem within 28 minutes.

Linewize Filter experienced degraded service in the Australian region for 28 minutes, impacting the ability to view parents, users and groups, run syncs, receive timely red flag alerts, and access Classwize logins. The affected components included School Manager and Classwize, with the engineering team working to restore normal service levels.

Linewize's Mac Agent version 3.7.3 automatic update caused high memory usage and intermittent internet connectivity drops on certain Mac devices. The issue was specific to the auto-update process, while manual installations of the same version remained stable. The engineering team identified the root cause and deployed a hotfix, with temporary workarounds including full reinstallation of the agent or switching affected devices to DNS filtering mode.

A Microsoft browser update caused Linewize's browser extension to fail starting automatically on some Windows devices using Microsoft Edge, resulting in webpages loading indefinitely or hanging during startup, particularly on lower-specification devices. The issue was identified as a conflict between Chromium engine changes and the extension's initialization process, which caused browser saturation and timeouts that prevented proper web filtering. Linewize's engineering team developed an architectural redesign of the extension startup process and deployed partial fixes while working toward a complete solution through quality assurance testing.
