It used to be a 25 hour flag. 1 day plus an additional hour.

I think (yes, that says I don't know) the period being longer than 24
hours had something to do with an attack to get relays under adversary
control in the right position to become a HSDir for some
hidden-services. If one pays for a relays by days an additional hour is
an additional day for an attacker.

I may have missed something, but maybe it was raised.

I do remember that changes to Guards took place, like requiring them to
have more bandwidth and to reducing the number of Guards clients would
use. This was due to research.
