In case anyone wonders just why the posting rate dried up, I got ‘shaped’ by my ISP. The effort involved in moving to an ISP offering a more generous data tranfer limit is too difficult currently, not least because nobody in our area can provide the high data transfer rates we depend on to function (meagre as that is by world standards).
Tomorrow the shaping is lifted and the posting rate will return to ‘normal’, which might be a good thing… I’m not sure.
