Sudden changes to speed & latency.....why?

About 10 days ago during some overnight Plusnet maintenance to one of its systems my Gateway changed, as I had expected. However, my fibre speed dropped markedly & my latency doubled. During this period my speed checks also became very erratic. I have tried a couple of Gateway changes but with no positive result.
When I logged on just after 6 AM this morning I checked as usual & lo & behold both my speeds & latency have returned to their previous values. My Gateway hasn't changed.
Is anyone able to provide me with an explanation? If so I will be most grateful.

Sounds like Fibre DLM to me!

Quote Fibre DLM to me!
Thanks Kelly. Over which neither you nor BT have any control?

We can't influence the Fibre DLM. It's looking at the errors/stability of your line and making its own decisions. Perhaps you were on a threshold and the maintenance disconnection triggered it, but because your line was stable for that whole period, the next disconnection let the DLM relax a bit
