[August 8, 2023]

These changes are essential only if you’ve previously whitelisted our uptime monitoring IPs in your firewall; otherwise, no action is required on your part.

The changes below will take effect on August 15, 2023. However, you can make modifications to your firewall at any point until then.

We will be gradually introducing the new nodes into production to minimize the negative impact on the users who should have made changes to their firewalls but didn’t, as explained in the following guide (step 5): https://docs.hetrixtools.com/how-do-we-perform-uptime-monitoring-network-changes/

After September 25, 2023, all new monitoring nodes will be fully used in production.
