Comment (by karsten):

 Replying to [comment:9 irl]:
 > Yes, I meant a new document type. I can't remember the reasoning for
 removing these from the bandwidth document, which I why I suggested the
 addition of a new document type with more detail. If we added back 1_week
 to the document, and dropped 3 days from Atlas, I think that is very
 reasonable and an improvement on the current situation where those graphs
 do not have data.

 The reason for removing graph data for 3_days and 1_week is that relays
 stopped providing bandwidth histories per 15 minutes and instead switched
 to bandwidth histories per 4 hours.  And we already provide graph data on
 a detail level of 4 hours for an entire month, so there was no (obvious)
 reason to provide a data set for 1 week or 3 days with the same level of
 detail.

 By the way, let's look at the numbers before deciding something: Of 10,651
 bandwidth documents with graph data for 1_month, only 1,277 or 12% still
 have graph data for 1_week.  We might just remove these graphs in Atlas
 regardless of whether there's data or not (as twim suggests above, when I
 didn't check the numbers...) and call it a day.  That wouldn't even
 require any changes to Onionoo.
