Affected almost everything connected to the network within FNWI (Heyendaal East)

The router that regulates all IP traffic between subnets in the Huygens building and surrounding buildings, became too busy. All network traffic, especially UDP had problems. ISC network admins reduced the load by simplifying the ACLs and reducing logging. At about 12:00 the problem was temporarily solved. C&CZ will do a further inspection of all ACLs, with the aim to reduce the load on the router without reducing security for connected systems.
