DESCRIPTION:Single peering interfaces can get loaded during peak usage and/
 or failure scenarios while the network as a whole still has spare capacity
 . As remedy we can use upstream via our so-called overflow providers. In n
 ormal operation mode we will prefer direct peerings and only use overflow 
 providers as fallback.\n\nFor events like the European Football Championsh
 ip we want to be able to shift traffic to those fallback routes with low e
 ffort\, low wait times\, high granularity and high confidence.\n\nWe have 
 implemented a service that injects on-demand copies of the existing fallba
 ck routes with the preferences tuned to let them be preferred over the "no
 rmal" peering routes. The routes are advertised via BGP sessions to our ro
 uters and are not distributed any further. The service is using GoBGP and 
 running in Kubernetes.
