  • ResolvedUTC

    This issue has been fixed.

  • UpdateUTC

    We have identified an issue with the China-route provided by CUG, as it appears to be missing certain IP block. Consequently, these IP block are being routed through NTT/PCCW, leading to suboptimal performance. We are currently in communication with the supplier to address and resolve this issue.

  • UpdateUTC

    As a result of the revised peering policy between AS9929 and AS4134, AS4134 is no longer accepting new prefixes from AS9929. In response to this change, CUG has implemented a solution by transitioning to AS4837. This adjustment effectively addresses the routing connectivity issue with AS4134.

  • MonitoringUTC

    The vendor has resolved filter-related issues, and we are currently witnessing a return to normal levels of inbound traffic.

  • InvestigatingUTC

    We have noticed a decrease in inbound traffic from CUG following maintenance, and we are currently investigating the prefix filter issue with CUG to confirm its impact.
