> In regards to "being in the office": most people will do this from home after sleeping most of the night and waking up to an alarm and then coming in a little later the next day. There are a few hardcore ones out there that prefer to pull an all-nighter and do so from the office, although my mileage has been those are quite few and far between.

DevOps/Admin here! I prefer the all-nighter, but I've almost always (in 14 hours) done it from home unless physical hardware had to be moved (i.e. forklifted datacenter to datacenter).
