A global IT outage has caused chaos at airports, banks, railways andbusinesses around the world as a wide range of services were taken offline and millions of people were affected.
In one of the most widespread IT crashes ever to hit companies and institutions globally, air transport ground to a halt, hospitals were affected and large numbers of workers were unable to access their computers. In the UK Sky News was taken off air temporarily and the NHS GP booking system was down.
Microsoft’s Windows service was at the centre of the outage, with experts linking the problem to a software update from cybersecurity firm Crowdstrike that has affected computer systems around the world. Experts said the outage could take days from which to recover because every PC may have to be fixed manually.
Overnight, Microsoft confirmed it was investigating an issue with its services and apps, with the organisation’s service health website warning of “service degradation” that meant users may not be able to access many of the company’s most popular services, used by millions of business and people around the world.
Among the affected firms are Ryanair, Europe’s largest airline, which said on its website: “Potential disruptions across the network (Fri 19 July) due to a global third party system outage … We advise passengers to arrive at the airport three hours in advance of their flight to avoid any disruptions.”
Everyone shitting on windows, yet this thing exists on Linux as well… I also started to dislike windows, yet this is not the time to be against windows users, this is to go against Cloudstrike together for even letting this happen.
I agree. I also think part of the blame can be placed on the system administrators who failed to make a recovery plan for circumstances like these -- it's not good to blindly place your trust in software that can be remotely updated.
In Linux, this type of scenario could be prevented by configuring servers to make copy-on-write snapshots before every software upgrade (e.g. with BTRFS or LVM), and automatically switching back to the last good snapshot if a kernel panic or other error is detected. Do you know if something similar can be achieved under Windows?
Sadly, I don’t know. I’m way worse with computers than I want to be, just careful about where I get my information.
It's the time to go against proprietary monopolizing software
Exactly, the blame here is entirely on Crowdstrike. they could just as easily have made similar mistake in an update for the Linux agent that would crash the system and bring down half the planet.
I will say, the problem MIGHT have been easier to fix or work around on the Linux systems.
Citation needed, my NUC running Fedora made it through this without a hitch
