Known issues: Unfortunately we had some network issues during this experiment. Issues were due to speed-tests in another part of the network, thought to be strongly separated using various rules in various switches. It turned out that some rules together with specific VLAN settings still enabled some cross-talk in certain situations, which caused packet-loss. In the end, the networks were physically separated to ensure no similar cross-talk could happen in the future. The UT time ranges with fully or partially lost data are: 10:00-10:30, 1140-1210, 12:35-1245. ================================ t2149sy START ================================= 2021-10-19 17:36:33 T2149 Start Message from SYOWA Station SYOWA has started T2149 recording with the source: 0454-234 at 17:30:00 UTC, 19 Oct.
