That's a lot of website that are now down... I find it impressive how terrible bigger services that are supposedly "redundant" are at reliability because of all the added complexity.
It happens... It's happened with S3, other AWS, Azure, GCP, and a number of other systems over the years. Seems to happen a couple times a year between them all.
That said, on self-hosting I've had outages that were self-inflicted more often than with cloud pipelines and CI/CD flows to production... in the end, it's probably a wash or favors cloud all the same. Even if it's more generally felt from cloud providers all at once.
Only your site is down, for the first time this year? You must suck at reliability!
Your site is down for the third time this year because of a Cloudflare or AWS outage, together with hundreds of others? Force majeure, can’t be helped.
