LINX (London Internet Exchange) are experiencing issues with their LON1 network today. This is causing brief periods of instability and BGP session outages across their network and has been seen across multiple switches now.
As a result, we have shutdown our LON1 peering until LINX confirm the issue is resolved. We still have peering established via LINX LON2, LINX MAN1, and EquinixIX Manchester as well as our global IP transit connections.
