New us-west-1 IP addresses start Monday

Hi there,

A quick reminder: on Monday, November 16, Checkly will start running checks in us-west-1 (N. California) from new IP addresses.

If you allowlist Checkly IPs on a firewall or WAF, add these addresses before Monday so your checks keep running.

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
