Last two dividend payments were 16.75 & 16.10 = 32.85.
This is ~ 10.95/day, because Tuesday was skipped. This may not be more hashrate, it could just be spreading 3 days' dividend payments over 2.
No they were down for about a day if you look at euligius, or maybe just eligius went down which would make sense with the 3 day thing.
