PacketStream - Connectivity outage in Tokyo – Incident details

Earlier connectivity issues in the Tokyo (TYO) region were traced to one of our upstream providers, where a distribution router failed to correctly learn a portion of MAC addresses. This caused excessive broadcast traffic and congestion on access switches, resulting in degraded connectivity for some routes.

According to the upstream provider, the affected router has been restored to production and network connectivity is now stable.

Our upstream provider has reported an issue in the Tokyo (TYO) region affecting one of their distribution routers, which may cause intermittent instability and degraded connectivity on certain paths.

We have engaged the upstream provider and they are working on remediation. We have applied mitigations on our side (including traffic rerouting where feasible) and continue to monitor closely.

Further updates will be provided as more information becomes available.
