BT OR provide a better optional SLAs on repair for the local loop
using "enhanced care".
Several business oriented ISPs support it. A search on "BT enhanced
care" should find it.
However - don't get your hopes up - that improves the underlying BT
Openreach "fix SLA" from 40 hours to 20 in business hours, so still
into multiple days of outage within SLA (especially if you use it
across weekends)
there is 24x7 with a shorter fix time from BT as well.
Traditionally - 4 or 5 hour fix is 1 of the big reasons to go for a
dedicated circuit tail based access - eg something based on BT EAD
Ethernet.
You also get some other stuff that may be useful - limited or no
contention in the service (you need to ask the ISP), fibre only based
access and symmetric bandwidth.
But then you are using a high end underlying tail circuit with mich
higher than connsumer based pricing and you can expect a corresponding
increase in charges.
For higher availability then resilience can be better than a single
circuit no matter what the SLA so dual independent tail circuits may
fit better
- as others recommended BT + VM cable based would give you logically
and probably physically separated circuits.
you were pointed at using a dual tail / load balancing router.
- with dual access, the router is likely to be the limiting factor for
reliability, so keeping a spare around in case of faults (and having
it pre configured and tested) may be a good idea.
