Looks like this also took down half of New Zealand's economy. https://www.nzherald.co.nz/nz/bank-problems-reports-bnz-asb-...

I was at the supermarket here last night about the time it kicked off. It seemed payWave was down, there were a few people walking out empty handed as they only had Apple Pay, etc on them. But the vast majority of people seemed fine, my chipped credit card worked without issue.

i've seen photos of the bsod from an affected machine, the error code is `PAGE_FAULT_IN_NONPAGED_AREA`. here's some helpful takeaways from this incident: 1) mistakes in kernel-level drivers can and will crash the entire os 2) do not write kernel-level drivers 3) do not write kernel-level drivers 4) do not write kernel-level drivers 5) if you really need a kernel-level driver, do not write it in a memory unsafe langua…

Took down our entire emergency department as we were treating a heart attack. 911 down for our state too. Nowhere for people to be diverted to because the other nearby hospitals are down. Hard to imagine how many millions of not billions of dollars this one bad update caused.

Contact a lawyer if this affected her health please. Any delays in receiving Stroke care can have injured her more I imagine. Any docs here?

Speaking as somebody who manages a large piece of a 911 style system for first responders and has done so for 10 years (and is not affected by this outage) - this is why we do not allow third parties to push live updates to our systems.

It's unfortunate, the ambulances are still running in our area of responsibility, but it's highly likely that the hospitals they are delivering patients to are in absolute chaos.

Wow, this hits close to home. Doing a page fault where you can't in the kernel is exactly what I did with my very first patch I submitted after I joined the Microsoft BitLocker team in 2009. I added a check on the driver initialization path and didn't annotate the code as non-paged because frankly I didn't know at the time that the Windows kernel was paged. All my kernel development experience up to that point was wi…

This is what I don’t get, it’s extremely hard for me to believe this didn’t get caught in CI when things started blue screening. Every place I ever did test rebooting/powercycling was part of CI, with various hardware configs. This was before even our lighthouse customers even saw it.

It's honestly terrifying that someone would opt for Windows in systems critical to medical emergencies.

I hope organisations start revisiting some of these insane decisions.

If true, this is insane that critical facilities like hospital do not have decentralized security system.
