All perfectly reasonable points.
Whichever hosting provider, I don't think downtime per se is something that needs to be too much of a concern - so long as it's not excessive, and comes back up within a reasonable time.
I am absolutely not casting aspersions on Noodles' server or his personal availability.
My question is purely and simply - what's the plan if he's abducted by aliens?
If something were arranged, such as the details of an alternative contact at the ISP in question (that could arrange access if the machine was switched off) were shared with at least two or three other ALUGers that would probably suffice. However, the list of people with those details needs recording somewhere so that they can be replaced, if they stop being an active member.
