McGraw Hill Education Outage History

From Feb 10, 2026 9:26 PM UTC, McGraw Hill Education began listing intermittent issues affecting the Higher Education - Connect / SmartBook service and eBook launches, with pages not loading and content access problems impacting student assignments and course materials. User reports surged around 9:00 PM UTC across multiple regions, indicating broad disruption as students attempted to access textbooks and SmartBook activities.

McGraw Hill’s updates attributed the degradation to DNS resolution problems on AWS, contributing to higher error rates and latency, with Microsoft-side issues later affecting ALEKS Excel tool questions. The provider issued a total of seven status updates between 2026-02-10 and 2026-02-13 detailing ongoing troubleshooting and progress.

Recovery began in mid-February, with ALEKS / Integrated Excel returning to normal by Feb 13, 2026 4:16 PM UTC and Higher Education - Connect / Excel Tools Service following at Feb 13, 2026 4:21 PM UTC. By that time, affected components were gradually restored, and user access to SmartBook and Excel-based activities improved.

McGraw Hill Education reported a brief outage affecting Open Court Reading within the ConnectED platform, with some users unable to complete OCR-related activities. The issue appeared to be limited to Open Court Reading and did not indicate a broader service disruption.

The outage started at Jan 30, 2026 3:46 PM UTC and was resolved by Jan 30, 2026 4:01 PM UTC, lasting approximately 15 minutes. The provider issued 2 status updates during the incident, outlining the issue and confirming restoration. Affected component: School K-12: ConnectED / Open Court Reading.

McGraw Hill Education reported a disruption in its Connect platform that affected login and assignment access. The outage began at 2:36 AM UTC with users unable to log in or load homework, quizzes, and other course materials. The issue affected two Connect components: the Higher Education - Connect / Login / Registration / Purchase path and the Higher Education - Connect / Assignment and Assessment System. Many users encountered gateway timeout or related errors when trying to access assignments, and login issues began to ease for some users around 3:01 AM UTC while assignment access remained degraded for longer. The incident impacted students across multiple locations in the United States.

McGraw Hill Education reported an outage affecting email delivery for some customers, with verification codes and other system-generated messages not arriving for recipients using Microsoft Office 365 hosted addresses. The issue was tied to an ongoing Microsoft O365 disruption that is impacting email delivery from external senders, including McGraw Hill. The outage began on Jan 22, 2026 11:11 PM UTC and was resolved by Jan 23, 2026 6:11 PM UTC, lasting approximately 19 hours. The incident affected two McGraw Hill Education components: Higher Education - Sharpen / Sharpen and ALEKS (US).

During the incident, the provider posted two official status updates as they worked with Microsoft to restore delivery and keep customers informed.

McGraw Hill Education faced a regional connectivity issue in the Asia-Pacific (APAC) region that caused intermittent latency and timeouts across its digital platforms. Users in APAC reported difficulties loading applications and creating or editing assignments. The outage began on Jan 9, 2026 8:31 PM UTC and was attributed to a regional ISP disruption tied to an undersea cable outage in parts of Asia, which disrupted network connectivity into McGraw Hill platforms. The impact was felt across two core areas: School K-12 Tools / my.mheducation.com and Higher Education Connect / login, registration, and purchase flows.

McGraw Hill communicated the incident through three official status updates, with connectivity gradually returning to normal by Jan 12, 2026 5:16 PM UTC. The outage persisted for roughly 2 days, 20 hours, and 45 minutes and was concentrated in the APAC region, rather than a global disruption.

A brief degraded performance affected dozens of McGraw Hill Education ConnectEd components across School K-12 and Higher Education Connect ecosystems. Users attempting to access core learning platforms, eBooks, assessments, and related tools may have experienced intermittent access or slower performance. The incident began on 7:31 PM UTC and was resolved by 7:46 PM UTC, lasting roughly 15 minutes. The McGraw Hill Education status page showed a transition from operational to degraded (warn) and then back to normal as services were restored.

The affected components spanned School K-12 ConnectEd and Higher Education Connect suites, including tools such as Reading Wonders, StudySync, iScience, Assignment and Assessment System, McGraw Hill eBook, SmartBook, Virtual Labs, and related learning services, among others.

During a planned maintenance window, purchasing on www.mheducation.com was unavailable from 11:01 AM UTC to 3:01 PM UTC. The maintenance impacted 22 components across MHEDUCATION.COM and Higher Education Connect, including First Aid Forward, McGraw Hill eBook, SmartBook, Virtual Labs, and the Login / Registration / Purchase workflow.

Users may have experienced limited functionality within ConnectED applications during this period.

McGraw Hill Education experienced an authentication outage that prevented many users from signing in across multiple product lines, including Higher Education Connect / Writing Assignment and LTIA Integration, as well as School K-12 ConnectED / OpenLearning services. Users reported blank screens, sign-in failures, and errors such as AS1-3 when launching assignments or accessing course content.
