Affected all users of the wired network at FNWI

After the network maintenance of 20141111 a single user reported later a problem with the wired network. These problems intensified and grew faculty wide on 20141119 at 13:34 hours. The network switches in the Faculty of Science received so many topology changes of the Spanning Tree Protocol (STP) that network traffic often stuttered. By curbing the STP traffic on 20141120 at 15:32 the stuttering disappeared. We still search for the exact cause, probably it is a housing move.
