UC San Diego's winter-quarter registration outages have put its new Triton Student System under scrutiny. Students said they could not secure some courses needed to graduate on time, raising concerns that delays could mean paying for an extra quarter. Associated Students organized a campus protest over the disruption.
Student Affaan Hassan described the outage to 10News: he spent more than six hours trying to register on Tuesday and ultimately secured his schedule. He said the disruption was being felt across the school. Other students told the station that classes filled while they were still trying to access the system.
The concern is that missing a required course could delay graduation by a quarter and add thousands of dollars in tuition, 10News reported. Third-year student Luna Vallejo told the station that transfer students are often trying to finish degrees within five or six semesters, while relying on scholarships and trying to avoid taking on debt to get the classes they need.
A System Built to Replace an Outdated One
UC San Diego said the Triton Student System was implemented for student class registration in July 2026, according to UC San Diego Student Affairs. Per 10News, the university launched TSS in the fall to replace WebReg, the school's former enrollment system, which officials said had known vulnerabilities.
UC San Diego's Educational Systems Renewal office has acknowledged ongoing problems since the rollout. The office said teams continue to address remaining issues impacting Fall 2026 booking, and noted that some approved course changes may not yet be reflected in TSS due to a current course-approval processing backlog. The office said it is tracking Schedule of Classes problems in a document updated daily, though it also said the Schedule of Classes was available for student planning and booking activity, with most course information listed as expected.
UC San Diego's IT status page has separately flagged trouble with the system, stating that ITS was investigating possible issues with TSS that could leave services slow or unavailable. The status page later said ITS had implemented a fix for the issues and was monitoring the situation, though the evidence does not indicate exactly when those updates were posted or whether service had been fully restored.
Surveys Point to Widespread Frustration
Student dissatisfaction with TSS surfaced well before the protest. A survey of 1,197 students found that over 73% rated their experience with TSS very poor, and nearly 80% said it was worse than the previous system, according to the UCSD Guardian in a report published in late September. The same outlet reported that TSS launched without a visual weekly schedule, and that a later class-planning tool could not actually book classes and was not directly available through the TSS portal.
A separate survey from Associated Students, conducted after TSS's first enrollment round, received 1,295 responses, with 98.5% of respondents saying the interface was worse or much worse than the previous system, the Guardian reported in a follow-up piece. According to 10News, UC San Diego's own student government survey drew more than 1,200 responses, with 98% of respondents rating the system poor or very poor. The university has acknowledged that TSS currently lacks a tool that would allow students to change their majors or minors, 10News reports.
Student Leaders Push for a Fix
ASUCSD President William Simpson and Vice President of Academic Affairs Kieran Matsuoka-Nguyen have said student leaders are meeting with TSS administrators to convey student concerns, according to 10News. Associated Students is collecting accounts from students who say they have been unable to access classes they need, and student government is pushing the university to restore access to required courses. Student leaders are also calling on the university to deliver a clear system-improvement plan, per the same report.
Some of the frustration echoes a past campus rollout. UCSD Deputy Chief Information Officer Kevin Chou recalled disruptions to student life after the WebReg launch in 2014, according to the UCSD Guardian, suggesting that growing pains with new enrollment technology are not entirely new to the campus.
What the rollout and tuition policy establish
UC San Diego’s Enterprise Systems Renewal office said TSS’s initial release was designed to provide basic, mission-critical capabilities, not full feature parity or a fully polished experience from day one. The office also said the system does not let students view multiple course sections side-by-side, an intentional design choice it said was meant to protect against slowdowns and security risks from automated scraping, according to UC San Diego Enterprise Systems Renewal.
UC San Diego says undergraduate tuition is adjusted for each incoming class and then remains flat until graduation for up to six years under its tuition stability plan, according to the undergraduate registration fees page. That policy alone does not establish what an individual student would owe for an additional quarter.
A UC San Diego spokesperson acknowledged unexpected TSS outages during winter quarter enrollment and said the disruptions affected students' academic planning and well-being, 10News reports. The university said its teams are working continuously to address TSS issues, and noted that more than 25,000 students had successfully registered for classes as of the prior night. UC San Diego asked students affected by the outages to contact the TSS team directly at [email protected] for assistance.
