These are all Community ♦ bumps, separated by exactly one hour (They occur on `hour`:38:16 UTC). Could the bot be sedated please? We're a 4-questions-per-day site; a bump an hour is not good for business.

We used to have one bump per day. This is evident if you scroll down on the homepage and check the timestamps ([screenshot][3]).

Apparently the number of questions bumped per hour is a [configuration value][4]. Maybe this got tweaked?
