Connection to Maestro Server lost...updating with poor Internet

Finished both remote island Maestro/Flex-6000 updates to 1.9.9.20 The W9EVT update of his Maestro and Flex-6300 was easily accomplished by patching the router in use to another network with Internet access. A fifty-foot Ethernet cable did the trick. My island QTH Maestro and Flex-6700 ended up a more complex process as the Island's DSL based Internet commenced acting up. The process stalled and/or failed several times, an example above in the picture of the loss of Maestro Server connection though Internet was accessible and similar glitches. It wasn't possible to keep everything solid long enough to update the radio, so that portion was done from the shack computer after six tries to download the 1.9.9 installer a full download was achieved. Now updated the station is all on 1.9.9.20 and all parts seem happy! A couple thoughts - down the road could one Maestro "seed" another Maestro/Radio ? Could a locally presented pre-downloaded update file be simply verified by the Maestro server to minimize the connectivity and data load when actually out at the remote site? Suggestions aside the installers are robust enough to work through bad conditions and everything worked in the end. Thank you, 73 Steve K9ZW
