Thank you for your advice.
I have bought 1200VA Cyberpower (preferred this one to EATON brand for better features).
One consideration was a potential noise from the UPS unit - hence consideration for smaller units.
Also, it is a bit bulky and heavy.
But - if you gotta have it you have to cope with it!
UPS is up and running.
Charged, installed software, connected PC, modem and 2 monitors (just enough - 4 outlets at the back so it is a saving on extra powerboard cost - (just kidding)) and is using ~50W (my PC is a Barebone Gigabyte Brick hence power demand is minimal). Status monitor says it has remaining battery runtime of 59 minutes now.
50mbs is it copper lines (like telephone ADSL/VDSL ?)
the reason i'm asking, even if my system is equipped with UPS and i can run
for some time my trading operation, i have two internet connections with
two different technologies, because my cable connection dies when a
power cut happens (because the amplifiers in the streets are out of power)
while my ADSL line keeps working (it does not need power in the street
to keep functioning)
my cable connections is 100mbs while my ADSL is only 15mbs...
have you validated that ?
the bottom line is that in order to orderly shut down, it involves more than
the perimeter of my own office
In good areas 50-60Mbs over copper is readily available as the copper only runs from the street box to the house and the exchange<->street box lines have now been duplicated with fibreoptics, just leaving voice on the old long wires.
That said I have also been impressed with recent 4G phone speeds, my iPhone 5 is now nearly 2X faster upload on 4G than home connection and not far off on download, so that is also a clear alternative backup if the area is alright.
The throughput on copper depends on the distance from the central phone building. Very quickly (> 5km) it drops to 15mbs, 50-60mbs will only be in city center at few km from the central switch...
I have also seen fiber coming, many countries have it, that will be better than the old copper.
As I said, that is why they replace the copper link with fibre-optic links in parallel, from the central phone building to the street box. Then the last NN hundred yards just over copper to the house doesn't matter.
I have 50+ Mb, no problem, ping 12ms to London. I agree it is a problem for areas that have no parallel fibre installed.
Of course, all is vulnerable at some level, hence the second alternative 4G backup, but then of course the tower masts can lose power too. Just depends how big the EOTWAWKI clouds get.
