that is in your head because you have no idea of network engineering, or redundancy
and IMO - you have no idea of what the word 'reliable' means
I have a great quality torch - and in the torch has a high quality battery --
the battery goes flat and the torch stops working
does that mean that the torch is unreliable? ------------------ no
if the battery is flat when I need it and all it needs is to charge and it's powerful, bullet proof, high performance and has a solid long working life -
then - the torch is VERY reliable --------- the operator is the problem
I say again - you have no idea of what reliable is
