If your website uses a firewall, WAF (Web Application Firewall), or security plugin that blocks unknown traffic, you may need to whitelist StatusDrift’s monitoring servers. This ensures our checks aren’t blocked and your uptime data remains accurate.
Why Whitelist StatusDrift IPs?
Security tools often block or rate-limit requests that appear automated or come from unfamiliar sources. This can cause:
- False downtime alerts – Your site is up, but our monitors are blocked
- Inconsistent monitoring – Some checks pass while others are blocked
- 403 Forbidden errors – Your firewall actively rejects our requests
- Timeout errors – Requests are silently dropped or delayed
Whitelisting our IP addresses ensures StatusDrift can reliably monitor your site without triggering security measures.
StatusDrift Monitoring IP Addresses
Our monitoring servers operate from these IP addresses. Add all of them to your whitelist to ensure checks from all monitoring locations succeed:

Whitelisting by Platform
Cloudflare
1. Log in to your Cloudflare dashboard.
2. Select your domain.
3. Go to Security > WAF > Tools.
4. Under IP Access Rules, add each StatusDrift IP with action “Allow”.
Alternatively, create a WAF custom rule:
Rule name: Allow StatusDrift Monitoring
When: IP Source Address is in {list of IPs}
Then: Skip all remaining rulesAWS WAF
1. Open the AWS WAF console.
2. Create an IP set with all StatusDrift IP addresses.
3. Create a rule that allows requests from this IP set.
4. Add the rule to your Web ACL with the highest priority.
Sucuri
1. Log in to your Sucuri dashboard.
2. Go to Firewall > Settings > Access Control.
3. Add StatusDrift IPs to the Whitelist IP Addresses section.
4. Save your changes.
Wordfence (WordPress)
1. Go to Wordfence > Firewall > Blocking.
2. Click Whitelisted IPs tab.
3. Add each StatusDrift IP address.
4. Click Add for each entry.
Nginx
Add to your server block or http block:
# StatusDrift monitoring IPs
allow 129.212.187.132;
allow 129.212.240.150;
allow 147.182.159.131;
# ... add remaining IPs
# deny all; # Only if you want to block all other IPsApache (.htaccess)
If you’re using Apache with IP restrictions:
# Allow StatusDrift monitoring
Require ip 129.212.187.132
Require ip 129.212.240.150
Require ip 147.182.159.131

# ... add remaining IPsWhitelisting by User Agent
As an alternative to IP whitelisting, you can whitelist based on our user agent string:
StatusDrift-Monitor/1.0 (+https://statusdrift.com/bot)Note: User agent whitelisting is less secure than IP whitelisting because user agents can be spoofed. Use IP whitelisting when possible.
Testing Your Whitelist
After whitelisting StatusDrift IPs:
1. Go to your monitor in the StatusDrift dashboard.
2. Click Test Now to run an immediate check.
3. Verify the check succeeds without errors.
4. Monitor for the next few hours to ensure consistent results from all locations.
Rate Limiting Considerations
Even with IP whitelisting, rate limiting might affect monitoring. StatusDrift makes requests at the interval you configure (e.g., every 1 minute). Ensure your rate limits accommodate:
- One request per monitor per check interval
- Requests from all monitoring locations (if multi-location is enabled)
- Additional requests during incident verification
For a monitor checking every minute from 3 locations, expect approximately 3 requests per minute to your site.
IP Changes and Updates
StatusDrift strives to maintain stable IP addresses, but changes may occur when we:
- Add new monitoring locations
- Upgrade infrastructure
We provide advance notice for planned IP changes. To stay informed:
- Check the changelog regularly
- Enable email notifications for infrastructure changes in your account settings
