We are currently investigating an issue affecting the Frankfurt Secure Connect Data Centers. Customers connecting through the anycast FQDN (e.g., xxxx.sc.ciscoplus.com) and being routed to Frankfurt may experience service disruption. As a temporary workaround, we recommend connecting using the data-center–specific FQDN, which can be found in your Umbrella/Secure Connect dashboard. For example, to connect to Amsterdam, you may use: xxxx.ams1.sc.ciscoplus.com. Please note that not all customers are provisioned for every data center, so ensure the FQDN is listed in your dashboard before switching. We will provide further updates as more information becomes available.
