Is Sucuri, Inc Down?

Sucuri has deployed additional Web Application Firewall (WAF) rules to help mitigate attack patterns associated with the recently disclosed critical PHP vulnerabilities, CVE-2026-109618 and CVE-2026-109619. We are monitoring these protections and related traffic. These rules provide an additional layer of protection for traffic passing through the Sucuri Website Firewall. WAF protection does not replace patching PHP on your origin server. We strongly recommend contacting your hosting provider or server administrator to apply the appropriate PHP security update as soon as possible. The PHP Development Team has released fixes in PHP 8.5.12, 8.4.27, 8.3.36, and 8.2.35. Your operating system or hosting vendor may also provide patched packages. Please review the official PHP security advisory for remediation guidance. https://www.php.net/archive/2026.php#2026-10-21-5

This incident has been resolved, and connectivity has stabilized across the affected region. While some carrier and subsea cable restoration activities remain ongoing across parts of Asia, network conditions have returned to a stable state. Visitors accessing your sites from affected regions may still experience minor increases in latency or slightly slower load times until all restoration work is fully completed. We have proactively routed traffic through the healthiest and most reliable available network paths and will continue to closely monitor connectivity, performance, and traffic conditions to ensure your sites remain available, protected, and performing as expected. If you continue to experience any connectivity or performance issues, our Support team is available to assist. Thank you for your patience and understanding while this incident was being resolved. --- [2026-09-22T15:00:42.735Z] (identified) We are currently experiencing network degradation affecting connectivity in parts of Asia due to multiple concurrent subsea cable outages impacting our upstream provider's backbone capacity. A new outage affecting the C2C cable system has occurred today and is contributing to the packet loss currently observed in the region. As traffic is being rerouted across the remaining available network paths, customers may experience intermittent packet loss, increased latency, and potential connectivity degradation when accessing services through affected routes. Our upstream provider is aware of the issue and is actively working to restore the affected network capacity. We are closely monitoring the situation and will continue to provide updates as additional information becomes available. Please note: Any estimated restoration times provided by the upstream provider are tentative and may change as the investigation and restoration efforts progress. We apologize for any disruption this may cause and appreciate your patience while the upstream network infrastructure is being restored.

This incident has been resolved. --- [2026-09-03T22:40:07.234Z] (monitoring) The degraded performance is over and we are monitoring the results. --- [2026-09-03T22:11:42.478Z] (investigating) We are continuing to investigate this issue. --- [2026-09-03T22:10:27.979Z] (investigating) We are currently experiencing degraded performance in WAF Cluster 3. Our team has identified network instability affecting traffic routed through this location, which may result in intermittent connectivity issues, increased latency, or temporary unavailability for some customers. We are actively investigating the issue and working to restore full stability as quickly as possible. Updates will be provided as more information becomes available.
