So yesterday, when I visited SO, I saw it down for maintenance. The login was disabled & SO was running in a different mode of SO.
I couldn't help wondering, how SO keeps track of the consecutive days (and adds +1) at that particular moment, even though I was not logged in.
Maybe it's silly & I didnt look closely enough, but now that the time (of server maintenance) is over, I'd rather ask if anyone could share what they know.
