Hmm.
How far apart are the 2 servers?
As an EMIS user, if I were an EMIS customer, I'd ask that, but I'm not,
like all English GPs.
I'd still wonder whether the two centres (assuming the 2 servers are
actually in two different buildings, and not in wings of the same, as
happened outside the oil storage depot's perimeter fence a few years
ago) have two separate, independent, geographically divergent routes
connecting them to Exeter.
Within Exeter I'm perfectly well aware that I don't have two independent
routes out, although I do have two buildings, and thus a quick move of
machine could improve matters in some rare cirumstances, despite EMIS
and the PCT frustrating the sensible[1] solution of using remote
desktops on our Windows 2003TS, but that is another problem, and more
like my problem.
Thought experiment time: What is the diameter of the smallest circle of
total destruction that I could notionally place on a map anywhere
outside the city limits of the city my practice is in, and cause EMIS'
remote hosted system to cease to function in my building?
That seems to me to be a useful and sensible metric - if it is 100
kilometres then we are into asteroid strike territory, if it is 10
metres then we are still in territory where the sensible person would
not go. For 100, 1000, 10000 metres there is range for discussion,
between blown fuse, rogue plumber, riot and deliberate action.
[1] for low, Windows compatible, values of "sensible".
