New IP addresses for us-west-1

Hi there,

On November 16, 2026, Checkly will start running checks in us-west-1 (N. California) from new IP addresses, in addition to the current ones.

Do you allowlist Checkly IP addresses on a firewall or WAF? Add these addresses before November 16. If you don't add them, checks that run from us-west-1 may start to fail.

IPv4

142.91.16.76

23.19.10.201

IPv6

2607:f5b4:2:10:2::/112

2607:f5b4:2:11:1::/112

Keep your existing addresses. They stay in use, so don't remove them.

No action needed if you

· Sync our IP lists automatically from our static IP endpoints

· Allow Cloudflare verified bots

· Don't allowlist Checkly IP addresses at all

Read the allowlisting guide
