New in icestat: information about the internet uplink(s).

Unfortunately it works very spotty, since the Bahn website is returned frequently instead of the API – including the mismatching TLS certificate. According to the DB twitter account, this is a known problem and the appropriate team is fixing it. Also, clear your browser cache, because why not.

Sources for icestat are on Github: https://github.com/octo/icestat

In letzter Zeit haben mehr und mehr ICEs wieder eine Variante des alten "ICE Portals". Selbstverständlich habe ich #icestat beigebracht mit den neuen APIs umzugehen.

Bericht der +Stiftung Warentest über das neue WiFi-Setup der Bahn. Der Fokus ist auf der Transferrate und dem Datenvolumen – nicht die interessantesten Metriken für meinen Anwendungsfall; für meine Arbeit sind Verfügbarkeit und Latenz viel wichtiger.

(Mein) Fazit: ganz brauchbar und tendenziell zuverlässiger als die Hotspots der Telekom. Die starke Varianz heißt aber leider auch, dass Arbeiten nicht auf jeder Fahrt möglich ist.
