Unless anyone knows another reason for this impressive increase in comments? Seems to roughly coincide with Sync launching. If thats the case, just goes to show the importance of good third party apps.

EDIT: Looks like a confusingly labeled graph and I think this is total comments. I have no idea why that spike could exist though.
federation with other previously unfederated instances full of comments. just a guess.
The chart is for 'all servers' already supposedly rather than from the perspective of a single instance though so would that be possible? Or can an instance exist sort of privately and then become visible causing a spike?
