There appears to be a wider network issue somewhere as suggested. Over the past two hours, some 50 odd people have stopped uploading and I can't see why - others are fine but the uploaders total is still falling slowly. Plusnet/BTW seems to be a majority.
TBB site is not accessible from here so latency graphs are failing. I had two RDI failures yesterday which is very unusual (Plusnet) and a lot of packet loss that I hardly ever see. Also Plusnet do have an alert active from yesterday that I found when I spotted my resyncs.
Edit:
I now have an ebay DNS failure....
