While reconfiguring the overlay SDN network on a newly deployed compute cluster at nLighten-Nürnberg, both route servers temporarily lost connectivity. Following the reconfiguration, the virtio network interface on the affected Debian-based Linux systems stopped forwarding traffic to the BIRD routing daemons. This issue was resolved through a cold reboot of the affected virtual machines.
We are currently investigating the root cause in more detail and apologize for any inconvenience caused.
To enhance the robustness and availability of local peering, we will introduce a third pair of route servers at a third DC by the end of August.
