There is currently a nationwide GSMR outage by the look of things and it is affecting multiple routes. Various trains are being restricted to 100mph as a result. Drivers are reporting issues registering and setting up the system correctly in the cab. If it can't be fixed imminently, the speed restrictions are set to be even more severe.
An upgrade was taking place and may or may not be related.
