Download speeds

I have noticed a few issues with downloading updates and/or stuff in the content manager.

On Tuesday I downloaded a few things at about 35Mb/sec as usual. Then I decided to download something and it was trickling down at 0.8Mb/sec. At the same time Azure voices became unavailable. A speedtest run on the same PC at the same time was lightning fast.
After a reboot, the same download flew down. I suspect a memory leak in the MSFS code that handles downloads
