After 2 years we moved the fastdl to another company for increasing our storage size. CPU, Ram, bandwidth connection should be the same pretty much, even the geographical switch is barely like 5 kilometers lol. Main thing is we went from 45GB of space to 120 GB. On the actual server machine we have about 33 GB free. Now that fastDL is not an issue any longer we only need to think about space on the dedicated machine or in the future to potentially get a second machine so that we finally could expand and get more servers again. peace!
