Pounce Zone File Sync - Daily Automated Zone File Synchronization
|
|
|
|
This script:
|
|
1. Downloads zone files from ICANN CZDS (app, dev, info, online, org, xyz)
|
|
2. Downloads zone files from Switch.ch via AXFR (.ch, .li)
|
|
3. Compares with yesterday's data to detect drops
|
|
4. Stores drops in the database for the Drops tab
|
|
5. Cleans up all temporary files and compresses domain lists
|
|
|
|
STORAGE STRATEGY (Ultra-Efficient):
|
|
- Raw zone files: DELETED immediately after parsing
|
|
- Domain lists: Stored COMPRESSED (.gz) - ~80% size reduction
|
|
- Only keeps current snapshot (no history)
|
|
- Drops stored in DB for 48h only
|
|
|
|
Run daily via cron at 06:00 UTC (after most registries update)
