Back in the days when I used to run a a pair of (very slow) ADSL
connections with different ISPs for each. I could expect broadband
faults on each line at least once a year (we are a very long way from
the exchange) Fortunately only once in 10 years did I have a fault on
both at once. So PN with their reasonable UK based support was a good
partner alongside my other ISP. Usenet access was a nice addition from
my point of view.
Fast forward to the last couple of years where we finally got FTTP,
which PN does not yet offer, the PN line has been relegated to usenet
access only (the connections are behind a load balancing router - who's
rules basically say WAN2 for everything unless it is usenet!), and
internet backup plus a phone line.
As backup internet <= 2 Mbps has very limited usefulness, and the days
of POTS are numbered. About the only other useful bit is the static IP.
Without usenet there is some doubt if retaining the broadband is worth
it. Perhaps if they finally get a FTTP offering (which I see mention of
for H2 2021)?
I wonder how many times Openreach end up making two FTTP drops to the
same customer?
Also with FTTPs massive improvement in reliability one might argue that
the need for a backup service is less critical if you have a business
contract on the service with a decent SLA? Although there is some merit
in having a separate service that does not rely on the same back end
infrastructure all the way, there would be quite a bit of commonality[1]
with 2 x FTTP
[1] Although both ADSL lines were openreach, by fluke rather than
planning, the wires followed a different path from the exchange.
