Marking this 'high' and a regression. This had been deliberately engineered in Ubuntu to run once per day outside of normal work hours, with a random offset <1h to spread out the mirror load. The current behavior is not consistent with that design, and can be disruptive to the regular use of the system. (I experienced this today with my desktop going into a tailspin because my browser and apt were fighting for memory.)

This is a good thing, decoupling apt daily runs from the rest of cron, and ensuring other cron.daily jobs are not blocked by up to half an hour by the default settings of unattended-upgrades. However the policy chosen is to have the apt daily script run at a random hour of the day in a wrong headed attempt to reduce server load. This has the side effect of running unattended-upgrades at random hours of the day — such as business hours — rather than being confined to between 6:25am and 6:55am, using the defaults. A better policy would be to have the script activate at 6:00am plus an interval of 20 minutes at one second intervals reducing the impact of timezone population spikes, while still allowing unattended-upgrades to run within a predictable interval, before 7am. At the very least, some sort of note in the NEWS file detailing the new behaviour would be welcome.
