Monitoring -
Cisco Engineering has confirmed that the DNS‑related issues impacting agent logins, state changes, Control Hub functionality, and Analyzer page loading have been resolved on the backend. While full DNS propagation across the Internet may take up to 40 hours, customers should already begin to see improved performance. Additionally, clearing the local DNS cache may help. This can be done by opening the Windows Command Prompt and running: ipconfig /flushdns before accessing the system.
Thank you for your continued patience and we will continue to update as and when we have more information.
