Re: Not just O2
In the US, at least, mobile operators and VOIP services were supposed to tell customers not to rely on the service for emergency services, as the networks don't have sufficient Ma-Bell approved reliability and resilience - as of a few years ago anyway. In other words, have a landline backup if you care about 24/7/365 availability guarantees for 999 service. Trouble is that no-one thinks about that nowadays, and the mobile network's probably almost always there. (Would be interested in the number of emergency calls missed due to network outages, presumably someone somewhere tracks that number.) Bet it's an infinitesimal fraction of the total number of 999 calls.
