For the last 3 days (since turning on the block) there has been a dead spot from China from 4:00 to 14:00 NZST.
@Dave@lemmy.nz you seeing the same drop?
Ah i missed your edit. I don't have per country data like that, I've only very recently played with removing Cloudflare from the equation and haven't set up any geo-location stuff yet. My requests are coming pretty evenly over the day though, up and down a bit bit depending on time but nothing like what you're describing. I'm looking at all traffic though, not just China.
