I tried to migrate a bunch of smaller images to this service several years ago, and then again about a year ago. The performance was not satisfactory back then and I found their docs recommended using it only for larger files [1] which to me makes the service significantly less useful for web assets, which I assume much of HN would use a service like this for.
Right, but its only been available in those two and AMS3, SIN1, SF2. So they cut 40% of the available options. And they only recommend using AMS3, so its possible the other are not far behind.
