WebPageTest (WPT) Agent IP Updates & Changes (Effective Nov 16)

No dark-mode styles — this email renders the same in a dark client.

Hi Emre,

On November 16th, we are migrating our WebPageTest (WPT) agents from Google Cloud Platform (GCP) to Amazon Web Services (AWS) to improve network performance and overall reliability.

 As part of this transition, several agent locations are being migrated to new AWS regions, while a few legacy locations are being retired. 

 If you whitelist IP addresses, you’ll need to update your rules before November 16th to keep your tests running smoothly. (If you don't restrict IP access for WPT agents, you're all set and can ignore this!) 

What You Need to Do 



	- Add the new AWS IP addresses below to your firewall allowlist.
	- Keep existing GCP IPs active alongside these new ones through November 16th to avoid any gaps while we make the switch.




	- Updated AWS Agent IPs
