Current suspicion on the German rails reddit is a software update gone wrong.
My personal suspicion, GSM-R is 90s GSM, they'll likely have a fried HLR & VLR because in any GSM network these are fundamental, without them you can't even get roaming from public phone networks working as there is no way for the public network to authenticate GSM-R subscribers.
