Problem Description:

There is fiber maintenance by Kt. Thurgau on the fiber between SBB station Frauenfeld and Kantonspolizei Frauenfeld.
This will leave the network access of PHTG without redundancy.
Network access is not affected for any SWITCH site - all traffic will be rerouted automatically.
In order to protect the 1G backbone in the east of Switzerland from overload we are forced to stop the peering with BelWü.
