Theres a hardware failure in the london datacentre where the TS server is located. Currently down, and has been most of the day.
Technition on site though, so hopefully the duff hardware will be replaced before tonights flight.
Yes, every TS install has the default public TS server contained in its bookmarks. I will set up a Flightgear channel there for tonight if the server is not fixed at T-30 min to flight.
