I'd annotated my LMs to let me know which RC channel they were on, plus my parcel was on BlueSteel. The RC restarts were in order Magnum, BlueSteel, LeTigre. and each channel roughly takes about an hour to be restarted - so I could plan my region hopping with minimal disturbance from the restarts. Following removal of the channel names in the server version the pattern didn't change, plus restart days haven't changed.
After this week's reshuffles, will have to see what the new timings are over the next few weeks.
