As part of our commitment to building a future-facing network, Imperva recently launched our Next Generation Architecture in the NRT - Tokyo, Japan PoP with improved capacity, connectivity, and services. This PoP is replacing our currently operational PoP in TKO - Tokyo, Japan. Imperva will be migrating all services and customer traffic from our TKO PoP to our NRT PoP, and decommissioning our TKO PoP during a scheduled maintenance window which will begin at 12-May-2026 15:00, completing by 13-May-2026 19:00.
For Cloud WAF customers, Imperva will reroute traffic to an unaffected PoP in the region for the duration of the maintenance, with no expected interruption to Cloud WAF services. At the end of the maintenance, traffic will be serviced by the new PoP. DDoS Protection for Networks customers must ensure that the advertisement of their ranges via an alternate connection such as GRE tunnels or Cross-Connects is in place prior to the start of maintenance to avoid interruption of service. At the end of the maintenance, DDoS Protection traffic will be serviced by the new PoP. If Performance Monitoring is enabled on the connections, you will notice a change in the IP address of the PM servers that are sending ICMP echo messages. This might require you to modify ACL/firewall configurations to allow ICMP traffic from the new IPs.
