    It feels like I keep hearing about such incidents. You'd think such high-end equipment would come with an alert module that contacts someone upon loss of power, temperature rise, or an exceptionally loud noise.

      I was director of engineering for an R1 research University and oversaw network services. I always joked that the most critical devices on our network were freezers, because if they had a problem and couldn't phone home we could lose millions of dollars of research.

      The freezers have modules that integrate with various monitoring and industrial control applications to report temperature and give alarm if outside of a given range. We usually dual fed the buildings with power from separate feeders and two disparate paths to the network core.

      Some buildings also had generators that would kick in, and all of this with automatic transfer switches. So we took freezers pretty seriously. Additionally, when a power outage was detected, the researchers would receive alerts as well so they could manually check their stuff, in addition to facilities and the noc.

      The most critical freezers were usually the -80 long term storage because they would usually have years worth of samples. We also had some odd facilities that had to be powered to maintain exact environmental controls for a large seed bank.

        Very nice. That's the stuff. Regularly tested, surely?

          I can't speak as much to the facilities side, but the network side we tested, and in theory the individual lab managers were responsible for testing the individual units. So probably hit or miss testing individual devices.

          We had the usual complement of monitoring devices, but we also put raspberry pi's running containers to create synthetic tests inside the customer vlans so we could test inbound and out, and we tested path failures during the day to build confidence in the resilience.

          I did work in operations for a while as well dealing with space, safety, capital design, etc. I will say the facilities folks did pretty good monitoring overall, and they worked closely with the utilities to deliver power on campus.

      i assume the failure is most likely to be human related (improperly set up, problems with other infrastructure, lack of maintenance or poor quality maintenance, etc). it doesn't matter how fancy...

      i assume the failure is most likely to be human related (improperly set up, problems with other infrastructure, lack of maintenance or poor quality maintenance, etc). it doesn't matter how fancy something is if they don't utilize it (surely there should be someone remotely monitoring every system like this, checking in like once a day for key info?? feels like there would have definitely been a huge change in temp even if some sort of other alert system failed)

        I still lean slightly towards this never having been set up at all, but you present a very real possibility. Reminds me of this saying that if you make but don't test backups, you don't have...

        I still lean slightly towards this never having been set up at all, but you present a very real possibility. Reminds me of this saying that if you make but don't test backups, you don't have backups.

        An automatic alarm should have gone out to those concerned, but it did not.

    Det rör sig om så kallade kryotankar som är fyllda med flytande kväve och ska hålla en temperatur på 190 minusgrader. Men den 22 december avbröts den automatiska påfyllningen av kvävet, något som Aftonbladet tidigare rapporterat om.

    These are so-called cryotanks that are filled with liquid nitrogen and must maintain a temperature of minus 190 degrees. But on December 22, the automatic filling of the nitrogen was interrupted, something that Aftonbladet previously reported on.

    Tankarna klarar sig i fyra dygn utan påfyllning, men eftersom det var julhelg hann det gå fem dagar innan det upptäcktes och temperaturen hade då stigit i 16 av tankarna. Varför är ännu oklart.

    The tanks can last four days without refilling, but as it was the Christmas holiday, five days passed before it was discovered and the temperature had then risen in 16 of the tanks. Why is still unclear.

    Ett automatiskt larm skulle ha gått ut till de berörda, men det skedde inte.

    We had a similar event during the big storms here last week at the marine station. The problem is that many of the freezers that this stuff is stored at -70 to -190 degrees, it takes a lot of power. The storms cut power to much of the region and their backup generator didn't work.

    Many time these university setups are good, but they are still running on university budgets and can go down. In many cases all it takes is one failsafe to slip and the system is down. Surprisingly common.
