EDIT - Hmm, after about an hour, all seems well again. That was weird.
On my EX42-NVME in Helsinki I’m seeing pretty poor speeds today that began like an hour ago. I had a huge download queue and was monitoring the rclone uploads to Google drive and saw they were transferring around 1Mb/s each to 8Mb/s each.
When I do a speed tests to my server this is what I see (would normally test 400Mb/s each way on my gig symetrical fiber at work)
