Update timeline
- investigating Dec 30, 2025, 01:30 PM UTC
We are receiving reports that customers with (explicitly on request) enabled symmetric DDoS protection are experiencing performance issues and lags with some applications. Regular (ingress-only) protection, active for 99% of customers, is not affected.
- monitoring Dec 30, 2025, 02:35 PM UTC
A fix has been implemented and we are monitoring the results.
- resolved Dec 30, 2025, 04:38 PM UTC
The fix worked as expected, and no further problems have occurred since then. The issue was caused by the switchover of traffic to our new Equinix PoP at the end of last night's maintenance work and only affected our firstcolo location, where some of our dedicated servers and colocation racks are operated. Other products such as IP transit, VPS, and web hosting are operated at other locations and cannot have been affected by design. Customers who had explicitly requested symmetric filtering at firstcolo through our support team were affected with an approximate probability of 50%. If your dedicated server does not have "fc-fra4" in its name, it's not operated at the affected datacenter.
