Episode notes
CDN Cache Misses Hurt Performance
- The current changelog.com site suffers from high origin latency and frequent cache misses on the CDN.
- Serving content directly from the origin or with low cache efficiency causes slower page responsiveness and delays in image loading.
Two Instances Caused URL Issues
- Running two isolated application instances pointing to the same database caused URL mismatches and logging inconsistencies.
- This led to podcast download count errors and Slack notifications posting outdated URLs.
Flyradar Reveals Global Instance Traffic
- Using flyradar, we can monitor all deployed instances globally in real-time, observing traffic and region distribution.
- This tool helps identify requests hitting different app instances and CDN locations, aiding troubleshooting and performance tuning.
