Placing Dedicated Interconnect connections in two separate edge availability domains within the same metro is important because maintenance windows are coordinated across edge availability domains within a metro, while maintenance windows are not coordinated across https://cloud.google.com/network-connectivity/docs/interconnect/tutorials/dedicated-creating- 9999-availability
