[freenet-support] Switching it off for a while

[Level 13]

I was wondering, what are the possible consequences if one switches
their Freenet node off for a while (say when going on vacation etc.)?
I mean, is there a minimum limit as to when a node is considered
"dead"? So if it comes back online in e.g. 1 month, will it be a whole
new "discovery" for it, or will it continue operating from where it
was before?
