Yeah, the IQI measurements are aggregated, but much lower than the continent map, which is only to Cloudflare. So the high bandwidth figure noted by parent is only for Cloudflare.

The map shows numbers from speed tests, which is only to Cloudflare, yes. But IQI's bandwidth numbers are lower because it displays average utilization (i.e. shorter requests, like web browsing, mostly capped by latency) while the map displays connection capacity.

I believe the parent was referring to the lines for Oceania being surprisingly good considering we usually think of it as being far away from content (which is not true when a large chunk of it can be served from local datacenters).
