Adding a little background-

This trace is from a school using an online test to our testing servers (which we do not own). The school is reporting repeated problems indicative of a drop or interruption in connection. I believe that there is not an issue on our end (the testing end) due to no dropped packets at our end.I don't see any clear pattern here of what could be causing the dropped connections (I am suspecting filtering on their end) so I am not sure what our next steps should be to assist them in resolving this issue.
