I also remember reports that 110 and 112 calls (German emergency numbers) were down for four hours in some county recently due to technical issues on DTs part.

I also remember reports that 110 and 112 calls (German emergency numbers) were down for four hours in some county recently due to technical issues on DTs part. I never saw an explanation what the exact cause was. Fire services and police handled it decently (iirc. stuff got routed to the next city and they increased patrol cars). Still a bit alarming that there's no fail over in place and these numbers basically rely on one company (probably routed in the fact that DT used to be state owned and is thus still implicitly trusted?).
