I am of the belief that the usage is getting close to the available bandwidth on the MSFS servers in some locations and at certain times. The fact that the updates are being pushed means that at peak usage time for a given region everyone trying to fire up is also having to download the update. Usually notice a rise in network related errors for about a week or so after an update lands. I did my update at about 2300 Pacific last night. Only got the 1GB and it took about 45 secs.
