Drop in Latency.......why?

[#1]

At around 8 am this morning I've just noticed a marked decrease in my latency. I didn't do anything & there's been no change in Gateway. Any ideas please from you experts?

Looks like interleaving has been reduced/removed.

Thanks Finguz.
Ah, that makes sense as my ping has also decreased & strangely enough my download has increased. Is this something that PN would have done or does it happen automatically?

automatically

Thanks Jim, it certainly seems to have helped.

Our connection has gone the opposite, Latency increased and we are getting Concentrator not reachable!
PlusNET has gone down hill for me ever since making the switch to FTTC

Hey.  We had one of our gateway drop a bunch of sessions at about 17:20 and you were one of those.  It looks like we've connected again now?
