The University of New Hampshire's Durham campus lost power in a significant outage shortly before midday on December 18, 2023. UNH Police posted a UNH Alert on both X and Facebook telling the campus that crews were working to restore power and that an update should follow within two hours; publicly available reporting does not establish the outage's cause or the exact time power was fully restored.

UNH Alert: UNH Durham Campus currently experiencing a significant power outage, crews are working to restore, anticipate an update within 2 hours
Verify this quote
UNH Police Department (@UNH_Police) on Xx.comfind archived copies
Posted at 11:21 a.m. EST on a Monday in mid-December, near the end of UNH's fall term, when a campus-wide outage would disrupt academic operations across campus
UNH Police cross-posted essentially the same alert to Facebook at roughly the same time, giving the message two independent official channels rather than one
The alert sets a concrete two-hour expectation for the next update rather than an open-ended 'stay tuned,' a specific commitment that is unusual among the outage alerts in this archive

Message elements

How the first alert is built

To check this alert, Claude (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

  • Hazardpresent25/25

    Final assessment

    Unanimous: 'significant power outage' names the specific hazard.

    What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.

    Final assessment

    Unanimous: 'UNH Durham Campus' is explicitly named.

    Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

    Final assessment

    Unanimous: the message is a status update with no protective action instructed to recipients.

    The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

  • Timepresent25/25

    Final assessment

    Unanimous: 'anticipate an update within 2 hours' along with 'currently' gives a clear timing/recency reference.

    When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.

  • Impactabsent1/25

    Final assessment

    Nearly unanimous: no stated consequence of the outage is given beyond naming it; one dissenting read treated the word 'significant' as conveying severity, but the majority sees that as describing the hazard itself, not a stated consequence.

    What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.

About this analysis
Context

Background

UNH Police issued a UNH Alert just after 11:20 a.m. EST on Monday, December 18, 2023, notifying the Durham campus of a significant power outage and telling the community that crews were working to restore service, with a further update expected within two hours. The same message was cross-posted to UNH Police's Facebook page, giving the outage notice two parallel official channels. Publicly available reporting reviewed for this case does not establish what caused the outage or precisely when power was fully restored to campus, only the initial alert's text could be confirmed verbatim from UNH Police's own social media posts. The outage fell near the end of UNH's fall term, when even a temporary loss of power to classroom and library buildings can disrupt academic operations.
Analysis

Key Findings

UNH Police committed to a specific follow-up window ('anticipate an update within 2 hours') rather than open-ended language, a concrete, falsifiable promise that most outage alerts in this archive do not make
The same alert text was posted to two separate official channels (X and Facebook) within a short window, reflecting a cross-platform posting practice rather than a single-channel release
The outage struck near the end of UNH's fall term, a timing detail that matters for impact even though the alert itself does not mention it
No secondary reporting (local news, student newspaper) confirming the outage's cause or exact restoration time could be located, illustrating how a real, verbatim-confirmed alert can still leave an incident's resolution undocumented in public sources
