Aug <var data-var='date'>21</var>, <var data-var='time'>19:47</var> UTC Resolved - We are no longer seeing elevated latency in IAD. Aug <var data-var='date'>21</var>, <var data-var='time'>19:39</var> UTC Monitoring - An upstream WAF provider is experiencing increased latency in the IAD region, which appears to be primarily affecting connections from AWS us-east to our API endpoints. Most traffic has been rerouted to nearby regions, so siteverify endpoints from servers connecting from AWS us-east regions that do not use our PrivateLink or Direct Routing options may see 20-50ms of increased latency until IAD is restored. Impact appears to be less than 0.005% of total requests, but may be concentrated on some network links.

Mar <var data-var='date'>15</var>, <var data-var='time'>04:00</var> UTC Resolved - hCaptcha APIs use several SSL certificate authorities, maintaining both primary and backup certificates; our CAA record is authoritative. We also automatically rotate certificates every three months as part of our security best practices. We received several reports today from customers running servers with outdated root CA entries. They either needed to update these after our most recent automatic certificate rotation, or had locked their validation for our endpoints to a specific certificate chain rather than relying on CA validation and our CAA records. Please ensure your servers calling the siteverify endpoint have an updated root CA store. This is an important security practice, as root CAs are occasionally compromised and removed from OS vendors' stores. Similarly, if you would like to enforce additional restrictions on validating our TLS certificates, please rely on the CAA record rather than hard-coding a specific intermediate chain.

Reminder: Please ensure your server's root CA certificates are up to date
