When the cloud has a cold: Lessons in resilience
October 9th - Azure Front Door takes a nap. Traffic reroutes, dashboards go red, and half the internet suddenly learns what "global edge dependency" really means.
October 20th - an AWS region (US-EAST-1) goes down. Not the apocalypse, just enough to make dashboards bleed red, engineers reach for coffee, and LinkedIn light up with "That's why we use multi-cloud" posts.
October 29th - Azure Front Door stumbles again. Same story, different day. And somewhere in between, a few other providers quietly joined the chaos with their own "we're experiencing elevated error rates" moments.
It's been one of those months when you realize: even the clouds catch colds. The uptime gods don't play favorites - not AWS, not Azure, not anyone.
And that's when Barry O'Reilly's Residuality Theory came to mind again - the idea that what really matters isn't the outage itself, but what's left behind.
The tangled complexity.
The assumptions that didn't hold.
The edge cases you dismissed with a confident, "That'll never happen."
Spoiler: it just did and will again.
