Investigation still ongoing...
Quick status update:
A member linecard of our backbone switch unexpectedly rebooted at 5:25 UTC (7:25 CEST)
The master routing service unintentionally switched over to the backup routing engine
OSPF and BGP sessions between our core switch and our edge routers were disrupted, which led to a total network routing outage
As far as we currently know, network switching was only partly affected
Network routing functionality recovered automatically at 5:30 UTC (7:30 CEST)
Root cause analysis is still in progress, further updates will follow.
