One more data point: when using simplestreams (actually running maas-import-ephemerals from maas) with a proxy, it takes several minutes before the proxy is actually used (i.e. before I see a hit in the proxy's log — and note that even though the log is only updated *after* the download, using wget to perform the exact same download shows it only takes 10 seconds or so). I was expecting that the first thing to happen would be the image download.
