Just p-f and n-s. Hecatoncheires was a vasilvv project, iirc, and I
have no idea what if anything ever happened to it.
p-f is also a test dialup; it would be _nice_ for it to retain power
during an outage but it would not be a requirement. n-s does not need
UPS power.
Thanks for the reminder about machine room access. I will try and
figure out scheduling for that when I next have a chance.
Apologies for the delay and thanks,
Anna
