Sucuri Outage History

Sucuri experienced SSL certificate issues in their Paris infrastructure following recent maintenance work, lasting approximately 1.5 hours. The SSL problems affected services in the Paris region. The team implemented a fix and monitored the system before confirming full resolution.

Sucuri experienced delays in applying changes made through the Website Firewall Dashboard, causing saves to take longer than normal to take effect. The incident lasted 45 minutes before the team resolved the propagation delays and restored normal apply times.

Sucuri experienced a sustained DDoS attack targeting their infrastructure in Paris, Frankfurt, and London regions, causing degraded performance, packet loss, and higher latency for services in Europe West and Europe Central. The attack initially focused on the Paris region but expanded to affect Cluster 28 across all three locations, with malicious traffic persisting for several days. After implementing a series of network mitigations over 108.8 hours, Sucuri successfully restored normal traffic levels and latency across the affected regions.

Sucuri experienced degraded performance in their Paris and London regions due to a DDoS attack that affected the Support Dashboard, Europe West, and Europe Central components. The attack was successfully stopped and mitigated by the team within 35 minutes. The incident was fully resolved after a monitoring period to ensure stability.

Sucuri experienced degraded performance in the London region due to network instability, affecting the Europe West and Europe Central components with intermittent connectivity issues, increased latency, and temporary unavailability for some customers. The team identified the root cause and applied corrective actions to stabilize routing in the affected region. The incident was fully resolved after 3.4 hours with all services returning to normal operation.

Sucuri experienced a network-related issue affecting traffic in the Paris and London regions, specifically impacting cluster 35 in Europe West and Europe Central components. The incident was caused by high traffic targeting a specific IP address, which required mitigations that kept sites on cluster 35 affected even after regional stability was restored. After 20.9 hours, all mitigations were lifted and normal service operation was fully restored.

Sucuri experienced intermittent network connectivity issues affecting their WAF/CDN services in the Asia East region, specifically impacting the Singapore point of presence (POP), which caused degraded performance for users in that area. The issue was caused by upstream network problems outside of Sucuri's infrastructure and lasted approximately 5.2 hours. The service has been restored to normal operation after the upstream network issues were resolved.
