Website Probes: Monitoring Station IPs

Last Updated March 14, 2014

This article includes the list of IP addresses we probe from. You may need this list to configure access through a firewall or to filter your access logs.

On Tuesday, 3/18/2014, CopperEgg will be doubling the number of probe test stations and associated IP addresses that are currently used to monitor your websites. We strongly recommend editing your probe configurations to select 3 or more stations as this will provide more accurate monitoring and fewer false positives. 

If you are monitoring resources inside your firewall, you will also want to review the StationIP Address List below and add the new station IP addresses to your firewall. (At the bottom of this post is a list of IPs formatted for quick copy and paste into your firewall...thanks to the suggestions of our Customers.) .
