This isn’t a gloat post. In fact, I was completely oblivious to this massive outage until I tried to check my bank balance and it wouldn’t log in.
Apparently Visa Paywave, banks, some TV networks, EFTPOS, etc. have gone down. Flights have had to be cancelled as some airlines systems have also gone down. Gas stations and public transport systems inoperable. As well as numerous Windows systems and Microsoft services affected. (At least according to one of my local MSMs.)
Seems insane to me that one company’s messed up update could cause so much global disruption and so many systems gone down :/ This is exactly why centralisation of services and large corporations gobbling up smaller companies and becoming behemoth services is so dangerous.
More generally: delegate anything critical to a 3rd party and you’ve just put your business at the mercy of the quality (or lack thereof) of their own business processes which you do not control.
Having been in IT for almost 3 decades, a lesson I have learned long ago and which I’ve also been applying to my own things (such as having my own domain for my own e-mail address rather than using something like Google) was that you should avoid as much as possible to have your mission critical or hard to replace stuff dependent on a 3rd Party, especially if the dependency is Live (i.e. activelly connected rather than just buying and installing their software).
I’ve managed to avoid quite a lot of the recent enshittification exactly because I’ve been playing it safe in this domain for 2 decades.
