brownouts reveal system boundaries
a day ago
- Infinite uptime is impossible; over-reliance on hyperscalers like Cloudflare hides system dependencies until failure occurs.
- Cascading dependencies can cause widespread failures, as seen in fintech disasters, affecting businesses and individuals.
- Backup plans are crucial and don't need to be complex—simple failover or offline copies can mitigate risks.
- Brownouts and chaos engineering (e.g., Google's internal brownouts, Netflix's Chaos Monkey) force constant testing of error handling and expose hidden flaws.
- Proposing mandatory annual outages for service providers to prevent architecture from assuming infinite uptime.
