Amherst College’s Week‑Long Network Outage Accelerates Shift to Cloud

Amherst College’s week‑long network outage, beginning February 11, brought campus‑wide Wi‑Fi, email, and essential services to a halt, highlighting the mounting pressure on higher‑education IT as institutions increasingly rely on cloud‑based solutions.

While the college was still diagnosing the root cause a week later, most problems were traced to equipment failures—faulty cabling, MAC‑flap incidents that flooded the network with unmetered traffic, and a configuration error on a central server. A third, as‑yet unidentified issue remained under investigation, according to The Amherst Student.

In short, after nearly a week of near‑complete connectivity loss, campus IT struggled to isolate the problem even though Amherst College owns and manages the majority of its network infrastructure. Unlike institutions that have migrated parts of their architecture to the cloud, Amherst’s IT maintained a largely on‑premises setup, using direct internet access and traditional SD‑WAN, which proved less resilient under strain.

Amherst College’s Chief Information Officer, David Hamilton, told the student newspaper that he had never seen a similar incident in his 12 years at the school and described the outage as “a confluence of accidents.”

The fallout was extensive: email and Wi‑Fi were down, dormitory card‑scanning systems that secure student housing were effectively disabled, students resorted to cellular data to access course materials, payroll and other administrative systems were inaccessible, and even campus laundry cards were frozen. Administrators could not provide a definitive cause by the end of the week, nor had they yet addressed reimbursement for the disruption, according to The Amherst Student.

A February 15 alert to the campus read:

"IT is working to restore services by moving them to the cloud. This is taking longer than expected because of the instability of the existing network."

Could this outage have been prevented? If campus IT had truly expected network conditions to remain static over the past decade, as their statements suggested, a major outage would have been inevitable. More importantly, the incident exposed significant blind spots: the campus did not appear to be conducting proactive network monitoring, which could have identified impending problems before they escalated.

Even networks that rely heavily on on‑premises hardware should deploy performance‑monitoring and diagnostics tools to alert staff to potential pitfalls in real time, rather than relying solely on the reputation of their hardware. Deploying these tools during the outage could have accelerated the mean‑time‑to‑resolution (MTTR) and helped pinpoint the root cause more swiftly.

Hamilton confirmed that Amherst will retire its hardware‑centric network infrastructure and migrate its central business systems to the cloud in pursuit of more secure and reliable connectivity for faculty, staff, and students.

While the situation is stabilizing, the prolonged outage could have been mitigated—or at least resolved faster—through modern network technology and dependable performance monitoring.
