This morning AS37678 (Botswana Fibre Networks) leaked all routes from AS6830 (Liberty Global) over the Linx routeservers causing issues for all providers having a peering session with the LINX routeservers as they would send all traffic destined for AS6830 to AS37678 instead.

The LINX has disabled the BGP sessions AS37678 has with the routeservers which resolved this situation.
