Hostinger has implemented server-level rate limits for traffic originating from specific network ranges, such as Meta, AWS, and Microsoft. These infrastructure-level protections are designed to maintain optimal server performance and ensure your website remains available for human visitors, even during periods of high-volume crawler activity.
This article explains how these measures may trigger an HTTP Error 429 (Too Many Requests) for non-human traffic and automated services.
Impact on third-party services
Because these rate limits apply to specific network ranges, you may notice issues with the following automated services:
- Social media platforms (Facebook, Instagram, WhatsApp): Link previews consisting of titles, descriptions, or images may fail to generate when you share your website URLs.
- Automation tools (Zapier, Make, n8n): Workflows or automations may fail when trying to fetch data from your site.
- Marketing and CRM tools (HubSpot, Salesforce): API synchronizations or data fetches may return errors.
- Monitoring services: Uptime tools may trigger false downtime alerts if their health checks are rate-limited.
Managing rate-limited requests
The rate limit applies at the server level to all customers and is not tied to your specific hosting plan or domain. These periods of high activity typically resolve within a few hours.
If you encounter 429 errors, follow these steps:
- Check the Hostinger Status Page for live updates regarding infrastructure performance.
- Wait and retry: Most crawler-related limits are temporary. Attempt the action again after a short period.
- Configure exponential backoff: If your third-party integration supports it, enable exponential backoff. This setting ensures the service automatically retries the request after a delay when it receives a 429 response.
These measures ensure your website remains stable and responsive for human visitors during traffic spikes from automated bots. Hostinger is currently refining these server-level protections to provide a permanent solution that balances high-volume automated traffic with third-party service compatibility.
NOTES
- These rate limits care applied to the server infrastructure, therefore, they cannot be disabled for individual websites or hosting plans.
- This behavior only affects non-human traffic; regular visitors can continue to access your content without interruption.
