McGraw Hill Education outage history

Users attempting to access McGraw Hill Education assignment pages experienced an outage starting at 2:29 AM UTC and lasting until 2:58 AM UTC. The disruption prevented loading of assignment pages and likely blocked viewing and submitting assignments for about 29 minutes. StatusGator detected the issue early based on user reports, ahead of any official acknowledgment from McGraw Hill Education; the provider did not publish an official status update during the window.

Early user reports began around 2:15 AM UTC and continued as the issue progressed, with a later signal around 2:45 AM UTC. Because there were no published updates from McGraw Hill Education, users experienced uncertainty about the status and potential deadlines. The incident is considered minor in scope given the short duration and the isolated impact on the assignment pages; service appears to have resumed after 2:58 AM UTC.

An outage affected mheducation.com, impacting the HigherEd and PreK-12 sections. Users attempting to reach the site encountered unavailable access starting at 1:01 PM UTC and lasting for roughly one hour and forty minutes while engineers worked to restore normal service. The provider posted ongoing updates indicating active investigation and efforts to restore access, with full restoration for both components by 2:41 PM UTC.

McGraw Hill Education faced a login outage that prevented access to MY.mheducation.com and multiple ConnectEd platforms used across K-12 and higher education. Users reported being unable to sign in or access coursework through direct login or LMS integrations, with password reset links failing and L500 errors observed in some cases. The disruption affected a wide set of components across the ConnectEd and OpenLearning ecosystems, including blocks like Building Blocks, StudySync, Reveal Math, Everyday Math, Music Studio, Networks Social Studies, Number Worlds, Reading Wonders, iScience, Redbird, My Math, AP Open Learning Titles, Arrive Math, Illustrative Math, Impact Social Studies, and Inspire Science, among others.

Users reported login failures, password reset issues, and intermittent L500 errors, with the disruption lasting into the early part of the incident.

StatusGator detected issues at Sep 23, 2026 1:32 AM UTC, about 1:45 AM UTC before McGraw Hill Education posted the first acknowledgement. Engineering and SRE teams investigated and began deploying a fix as updates progressed. By 2:31 AM UTC the status had moved from down to warn and then to up for many components as service validations completed. By 2:56 AM UTC higher education login and most K-12 modules were reported up and overall accessibility had improved.

Some students using McGraw Hill Education experienced crashes or loading errors when accessing certain SIMnet and SIMskills assignments. The impact began at 3:01 PM UTC and persisted for about an hour and a half, with services returning to normal at 4:36 PM UTC. Because the issue was tied to specific assignment workflows, the disruption appeared concentrated on these components and overall user reports remained limited.

Users of McGraw Hill Education reported that assignments would not load after selecting Show Me Guide Me or Let Me Try, with several users in the United States describing the page as stuck on loading. The problem appeared to affect the assignment loading flow rather than the entire platform, with reports from Riverbank, California and Bowling Green, Ohio indicating the issue occurred across devices. The incident timeline shows reports beginning around 2:15 AM UTC and continuing through 2:30 AM UTC as more users were affected.

Users attempting to access Actively Learn within McGraw Hill Education's School K-12 platform encountered errors starting at 4:01 PM UTC, with the Achieve3000 / ActivelyLearn component experiencing degraded access for a portion of users. The issue persisted for about forty minutes before services returned to normal, with the component resuming full operation by 4:41 PM UTC. McGraw Hill Education acknowledged the disruption, stating they were aware of the issue and actively investigating to restore normal functionality and would provide additional updates as they became available.

A partial outage affected McGraw Hill Education, with users reporting login issues, problems launching classes, and course content not loading across some platforms. Some class links returned unauthorized access messages and a subset of courses appeared unavailable. An early warning signal was triggered when users reported course content not loading around 5:34 PM UTC, lasting until 5:38 PM UTC. StatusGator detected the issue at Aug 19, 2026 5:34 PM UTC, roughly 29 minutes before the official acknowledgement.

McGraw Hill Education reports intermittent loading issues for Integrated Excel within ALEKS Question Bank assignments, starting around 4:21 PM UTC. The problem affects a subset of users and has persisted as engineers work with their technology partner, Microsoft, to identify the root cause and restore normal functionality. Through 12:36 AM UTC the updates describe the issue as intermittent and continuing, with no final resolution in sight.

The impact centers on the Integrated Excel component in ALEKS, which can disrupt assignment creation and submission for instructors and students. McGraw Hill Education has indicated ongoing investigation and remediation efforts as teams coordinate with Microsoft to resolve the intermittent loading problems and return ALEKS to full operation.

Students attempting Proctorio-enabled assignments in McGraw Hill Connect encountered loading problems that prevented them from starting work. The issue affected the Higher Education - Connect / Proctored Exams component, with users reporting being stuck on the Proctorio loading screen. The incident began around 5:46 PM UTC and McGraw Hill’s status updates show the team actively investigating the root cause with Proctorio.

A subsequent update noted that the problem also affected Integrated Excel questions within Question Bank assignments. That component briefly moved to up around 7:16 PM UTC, indicating a partial recovery for that piece while other parts remained impacted. The situation continued to evolve with ongoing investigation and communication, and as of 2:06 AM UTC the overall incident remained unresolved. User reports during the event were limited but documented symptoms included Excel questions failing to load and Proctorio not launching as expected.
