We have updated a new certificate with new IP ranges. Customers may see their agents appear to be offline or have trouble connecting to the control plane after a DNS change was made. We recommend they allow list the Fastly public IP range if they had IP based networks controls in place previously. Please let us know about any certificate issues as they should be transient. This may also impact Signal Sciences data collectors. New events from agents may not be processed by our back end services, agents may erroneously appear to be offline, and agents may not be receiving updated rules sets. Customers may experience also delays in data available in the Signal Sciences console.
