We are taking the MEX1 EDC site in Mexico out of rotation due to ongoing issues impacting anycast services, including DNS and Secure Web Gateway. This action is expected to mitigate most customer impact for traffic routed through this location. Some users may experience geo-blocking when accessing location-sensitive websites, including certain banking or government websites. Our engineering teams continue to monitor the service and work with carrier providers to restore normal resiliency. Updates and additional details will be provided as new information becomes available.
