Failover Timing Update — July 8, 2026
Change
Per Germaine's direction, the failover timing was updated:
| Parameter | Before | After |
|---|---|---|
| Check interval | Every 10 min | Every 5 min |
| Confirmation sleep | 60s × 4 cycles | 30s × 4 cycles |
| Total confirmation window | ~3.5 min | ~2 min |
| Max downtime before failover | ~13.5 min | ~7 min |
What was changed
- Cron on app1-bu:
*/10 * * * *→*/5 * * * * - Watchdog script sleep:
sleep 60→sleep 30(line ~71) - Confirmation message: Updated from "~3.5 minutes" to "~2.0 minutes" (lines ~68, ~96)
Rationale
Faster detection = shorter failover. 7 min max vs 14 min max. User prioritized speed over cost.
DR Plan impact
DR-PLAN.md and server-inventory.md should be updated to reflect:
- Server is warm (always on), not cold (boot on demand)
- Check interval is 5 min, not 10 min
- Verification needs to check both the cron schedule AND the sleep value
