This is just to let off steam about Deutsche Bahn's utter failure to provide (paid, mind you) wifi access aboard their trains.
Ping is used for measurement, the latest graphs are made with a 2-second resolution, older ones with 5s. I abort after 1000ms each try, so max latency is set to that. These and complete name resolution failure get assigned -200ms latency, so it becomes visually more apparent where total connection loss occurred. I'll just post more of them as they come in.
Bad latency, total connection loss after 1/3 of the ride:
Not even that bad.
Total failure of wifi system this time.
Usual shitty connection:
