In defense of GitHub's poor uptime

- GitHub's uptime appears poor, but uptime numbers can be misleading, especially with aggregated service data.
- GitHub's overall uptime is low (e.g., 89.43% over 90 days), but individual services like core Git operations have better uptime (e.g., 98.98%).
- Uptime calculations can penalize well-isolated services, making overall numbers look worse than the actual user experience.
- Incidents often affect only specific features or regions, not all services for all users, which aggregate numbers fail to capture.
- While uptime is still unacceptably low given Microsoft's ownership, criticisms like 'zero nines' availability are overstated; it's more a D tier than F tier.
