We are migrating our WebPageTest agents from Google Cloud Platform (GCP) to Amazon Web Services (AWS) on November 16, 2026 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.
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 9th to avoid any gaps while we make the switch.
