yes it was. EDIT: to clarify both downloads direct to slice using the update function and download to a windows PC from the site are slow.
much later , the following day ....... Update: if there is not an obvious reason, years of computing have taught me to think outside the box.... Gordon's download was slow, Portable Apps LibreOffice was slow but not much else.... .... having slept on it, I reset the QoS settings in my router to default and rebooted it: both slooooow downloads now work fine. Gordon's being the second one, and with a different source download server was the (tenuous) clue.
Happy now, and y'all no need to worry about a server issue at your end
Strange, very strange indeed.
