Again, a 4G (or similar) for back up might fail too.
When we had a major outage here, we lost our FTTC/VDSL connection, but retained voice telephony so an ADSL connection on a second line would have been available. The outage also affected mobile operators and their networks were seriously compromised for voice and data with complete non-availability at some locations.
What were the reasons for the outage?
