Hello again,
we'll set up a VM test environment here to simulate limited incoming or outgoing data transfers (similar to the scenario 1.3 MBytes/min "Session 96" and 3.4 MB/min "Session 111" in your 19-03-2019 LOG). So you'll see some downloads in the range of .00001 - .00010 in your next LOG files. We'll play a bit with timeouts. It's possible that we change "User-Agent: SB8" to "User-Agent: SB10" so you can filter our traffic.
Update 1: for your information. At the moment we are IP 37.81.163.174 in your LOG to simulate low-bandwidth connections and timeouts. You'll see more tests during the next few days in your LOG.
Update 2: I have attached a screenshot. This happens with Internet Explorer when a user tries to download the .00005 cluster file (about 10 MB) from a low-bandwidth connection (we have simulated "Session 96" with 0.17 Mbits/second). It simply times-out.
