Even before we had power issues in South Africa, garage and gate motors
had batteries in them. So it appears to be historical, for some reason
or other.
Pretty impressive. How do they do that in SA?
Providing backup power is not an issue in major data centres.
GPON providers also do rather well in keeping the lights on during an
outage. When outages were still relatively limited 5 or so years ago,
you couldn't keep your home link up for more than an hour during an
outage. Now with outages being more sustained, neither I nor a
reasonable sample of folk I know have had their GPON fibre out during an
outage, even when they occur multiple times in the day. I suspect decent
use of batteries and generators.
Wireless ISP's seem to be doing just fine too, as they, obviously, have
limited scale. Again, batteries and generators.
The mobile carriers suffer the most, as do operators who deploy Metro
PoP's in commercial buildings that aren't consistent with backup power
promises. The mobile operators are having to deal with battery theft and
incomplete battery recharges between multiple outages in a single day.
Mark.
