CrowdStrike is all over the news: the impact of the faulty security software is immense.
Some systems affected are safety-related (e.g. in Healthcare or Policing) and there will be some direct safety impacts, such as delayed treatments. Harder to quantify is the indirect effect: the mental (and financial) stress caused by major IT failures is huge. We wait to see what the root causes were, but we should not ignore the bigger picture: we have built systems, processes and services around commercial IT in a very fragile way when we know it can fail. Where were the workarounds, backups and alternate systems? This is definitely one for consideration in the 'Safer Complex Systems' Working Group.
