This network incident affected the services of Roubaix data centers from 5:01 p.m. to 5:40 p.m. CEST, as well as the backbone trafic that flows there.
Unfortunately Roubaix is hosting several network core components of the OVH global network.
All others customers on Azure, Google and Amazon were fully operational.
