End network issues: 14:40h, Mar 22, 2018
Problem description: Route leak
Problem location: atom86 network
Problem cause: Policy change
Sequence of events
On Thursday, March 22, 2018, 14:09 a configuration change was performed on both core routers
to adjust a policy for peers and customers. Due to a typo a full table was leaked to all peers.
BGP customers and peers have seen their prefix-limit tripped causing BGP sessions to drop.
Directly connected customers lost internet connectivity via atom86.
A rollback to the original configuration was performed at 14:40 to quickly resolve the issue. Then
the typo was fixed and the configuration was re-applied successfully.
Policy changes will be tested against test routers before they will be activated in the production
