I also wonder the cost differential.
Got me thinking about these incredible beautiful museums that are closed all night long… you’d still want someone there early enough to catch if the roof leaked so nobody missed their opening-hour tours. Back to libraries, bummer if I can’t renew my book online one night but would set reminder to try again later. Could affect my perception of my library’s tech prowess! That’s a risk for TIA! (Though I experience many a delay and downtime… perhaps my fault for using iCloud Private Relay like I bet scrapers sometimes abuse… but a few more hours overnight here and there wouldn’t be catastrophic for my current perception.)
Mainly would want overnight support to be cheap since stuff’s donation run. - Love TIA! An internet-billionaire should make history becoming a billionaire donor today (hope one’s reading this :) ).
