Dear Customer, Â We had a network outage at our eBRC Windhof datacenter this morning from 07:31 am CET until 07:59 am CET on December 10. From initial investigation, it appears that one of the core switches had a software issue, causing a network-wide flapping spanning-tree. Overall effect was that the switching fabric for our eBRC Windhof datacenter was unusable. Â To mitigate this issue going forward, we have make two changes. . We disabled an unstable link with was causing too many spanning-tree topology changes. . We also further tuned spanning-tree protection on every switch. Â Furthermore, we have a priority case open with the vendor to determine the cause of the issue as we did capture debug logs. Â We apologize for any inconvenience this may have caused. We'll continue to follow up with the vendor to make sure this issue does not happen again. Â Kind regards, Â The DATACENTER Luxembourg team |
