We are due to have a short planned downtime for our LIMS (1 hour) and I'm interested to see how other people would document this. I have a Business continuity SOP that we will follow and a risk assesment for short term downtime on the LIMS. The downtime will be before the bulk of daytime testing and it's entirly possible that it would have no effect on our work (we are a small DGH). Would you write a down time report to document any issues or just that it had all gone as planned or only raise a non-conformace if there were any issues?

Also if the downtime was not going to change anything in the LIMS would you still do some validation?
