IPv6 reachability from REY degraded

时间线

1. 已解决2024年10月3日 09:34 UTC

   IPv6 from REY has been fully reachable for 22 minutes. Duration: 1 h 18 min. IPv4 traffic was never affected.

2. 观察中2024年10月3日 09:12 UTC

   Síminn has corrected the policy and we see our prefix in their looking glass again. Watching for a full hour of clean probes before closing.

3. 已确定原因2024年10月3日 08:49 UTC

   Síminn is not propagating our IPv6 announcement beyond their network after a policy change on their side. We have moved IPv6 outbound to Farice, which is announcing us globally.

4. 调查中2024年10月3日 08:20 UTC

   Some IPv6 destinations are unreachable from REY since 08:16 UTC. IPv4 is unaffected. Our own external probes over IPv6 from the Nordics fail; the other probe locations succeed.
