Re: [gaia] Heterogeneity in network capacity: growing?

Seems to me the two likely bottlenecks are last-mile mobile links
(especially old devices), and international gateways.  Since international
bandwidth can be quite expensive (even with undersea fiber in some areas,
but especially without it), there is often throttling and/or congestion at
those points, even when your device has high bandwidth.
