We have identified and fixed the issue.

After enabling a feature for coredump reporting, the system has unexpectedly restarted all services, although we've instructed it not to do so. We will investigate further on why this happened and implement counter-measures to prevent such issues in the future.

We are investigating a crash of our router er2.cgn1.as200482.net. Traffic that was destined towards this router may not be routed anymore, and partial unreachability can be observed.
