Reputation will be off until tomorrow, apologies but this isn't an easy thing to fix - and given it wasn't a week, month, quarter, or year change...it'll fix itself completely tonight.
I'm sure you'll see a post-mortem of some sort about this later from our sysadmins, but we
have had a particular web server that runs our scheduled jobs, or kicks them off rather. Unfortunately this server ate it (repeatedly) last night before the reputation reset job got kicked off, so it didn't happen precisely at 00:00 UTC as it normally does.
We're not sure of the cause yet (diagnostics on the troubled hardware are underway) but we did some scrambling to get things back in working order, so everything should be good from here on out.
I'm going to status-declined this, but I hope you'll agree it's simply not worth the half-day time investment to fix the numbers just for a day already half over.
