ARC FCU: Provider Rate Limit Hit
Requests were throttled by the provider and must be retried after cooldown windows.
Likely causes
- Burst traffic exceeded provider request quotas.
- Shared API key budgets were depleted.
- Polling cadence was too aggressive for current plan limits.
Resolution steps
- 1
Back off requests and retry with exponential delays.
- 2
Reduce polling frequency for low-priority sources.
- 3
Upgrade provider quotas or isolate keys for heavy users.
Prevention controls
- Enforce per-provider concurrency and queue discipline.
- Monitor request budget burn rate in near real time.
- Use adaptive sync intervals based on connection health.
