Update - We are actively exploring potential mitigation options to address the sub-optimal routing and reduce the impact on affected origin fetch traffic. In parallel, we are working with the third-party provider to address the underlying geolocation issue. We will provide further updates as more information becomes available.
Aug 13, 2026 - 17:55 UTC
Investigating - We have identified a condition where a subset of customer origin fetch traffic from our proxy servers in the WDC PoP is experiencing sub-optimal routing. In these cases, origin fetch is getting routed to specific third-party CDN networks in the APAC region instead of Eastern US, which is resulting in increased latency for origin fetch, and ultimately reduced performance in website access. While we are working with the third-party CDN on to correct their Geolocation routing information, we are exploring potential workarounds within our equipment to override the sub-optimal routing which is currently in place.

We will provide further updates as more information becomes available.

Aug 13, 2026 - 16:53 UTC
Update - We have identified the source of the issue affecting the YUL (Montreal, Canada) PoP and are working on remediation. While completing the remediation may take an extended period of time, service has been stabilised by rerouting traffic through alternate Points of Presence (PoPs).

Traffic continues to be served through alternate locations, and we are not currently observing customer impact. We will continue to work towards restoring the YUL PoP to normal operation and will provide further updates as more information becomes available

Aug 13, 2026 - 09:29 UTC
Update - Traffic is now being served by other PoPs, and service has stabilised. Our teams continue to investigate the underlying cause of the issue affecting the YUL infrastructure and are working towards restoring the PoP to normal operation.

We will continue to monitor the environment closely and provide further updates as they become available. The next update will be no later than 09:18 UTC.

Aug 13, 2026 - 08:48 UTC
Monitoring - We have mitigated the issue affecting the YUL (Montreal, Canada) PoP by removing the affected PoP from service and redirecting traffic to alternate locations.

Traffic is now being served by other PoPs, and service has stabilised. Our teams continue to investigate the underlying cause of the issue affecting the YUL infrastructure and are working towards restoring the PoP to normal operation.

We will continue to monitor the environment closely and provide further updates as they become available. The next update will be no later than 09:05 UTC.

Aug 13, 2026 - 08:34 UTC
Investigating - We are investigating an issue affecting traffic reaching our YUL (Montreal, Canada) PoP. Customers may experience connectivity issues, increased latency, or service disruptions when traffic is routed through this location.

Our teams are actively investigating the issue and working to identify the root cause. We will provide further updates as more information becomes available.

The next update will be before 08:51 UTC

[ICM-5357] ORD to MDW PoP Migration - Chicago, IL Aug 25, 2026 08:00 - Aug 26, 2026 08:00 UTC

As part of our commitment to building a future-facing network, Imperva recently launched our Next Generation Architecture in the MDW - Chicago 3, IL PoP with improved capacity, connectivity, and services. This PoP is replacing our currently operational PoP in ORD – Chicago 1, IL. Imperva will be migrating all services and customer traffic from our ORD PoP to our MDW PoP, and decommissioning our ORD PoP during a scheduled maintenance window which will begin at Tuesday, August 25th, 2026 at 08:00 UTC, completing by Wednesday, August 26th, 2026 at 08:00 UTC.

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. To learn more, see https://docs.imperva.com/bundle/cloud-application-security/page/network-ddos/performance-monitoring.htm
