Hi,
we do have packetloss all through the evening since we reach the limit of 900 mbit now and then.
This is not related direktly to the download.
Currently we are lucky since we have only 850 Mbit in average at the moment.

Oliver,
This is just during your download test, correct? You
do see the single interface peak up to 850Mbps during
the evening with normal production traffic (not the
test download traffic), correct? Please clarify.
-Thanks,
Jared
